Abstract This paper presents a comprehensive techno–economic and environmental impact analysis of electric two-wheeler batteries in India. The technical comparison reveals that sodium-ion (Na-ion) and lithium-ion (Li-ion) batteries outperform lead–acid batteries in various parameters, with Na-ion and Li-ion batteries exhibiting higher energy densities, higher power densities, longer cycle lives, faster charge rates, better compactness, lighter weight and lower self-discharge rates. In economic comparison, Na-ion batteries were found to be ~12–14% more expensive than Li-ion batteries. However, the longer lifespans and higher energy densities of Na-ion and Li-ion batteries can offset their higher costs through improved performance and long-term savings. Lead–acid batteries have the highest environmental impact, while Li-ion batteries demonstrate better environmental performance and potential for recycling. Na-ion batteries offer promising environmental advantages with their abundance, lower cost and lower toxic and hazardous material content. Efficient recycling processes can further enhance the environmental benefits of Na-ion batteries. Overall, this research examines the potential of Na-ion batteries as a cheaper alternative to Li-ion batteries, considering India’s abundant sodium resources in regions such as Rajasthan, Chhattisgarh, Jharkhand and others.

In this study, electrical models for cylindrical/pouch-type lithium Li-ion batteries and supercapacitors were investigated, and the impedance spectra characteristics were studied. Cylindrical Li-ion batteries use Ni, Co, and Al as the main materials, while pouch-type Li-ion batteries use Ni, Co, and Mn as the main materials. Herein, 2600–3600 mAh 18650-type cylindrical Li-ion batteries, 5000 mAh 21700-type cylindrical Li-ion batteries, 37–50.5 Ah pouch-type Li-ion batteries, and a 2.7 V, 600 F supercapacitor are compared and analyzed. For a cylindrical Li-ion battery, the RS value of a battery with a protection device (circular thermal disc cap) is in the range of 14–38 mΩ. For the 18650-type cylindrical Li-ion battery with a protection device, the RS value of the battery is between 48 and 105 mΩ, and the protection device increases the RS value by at least 33 mΩ. A good Li-ion battery exhibits RS. Moreover, it has small overall RP and CP values. For the 21700-type cylindrical Li-ion battery with a protection device, the RS value of the battery is 25 mΩ. For the pouch-type Li-ion battery, the RS value of the battery is between 0.86 and 1.04 mΩ. For the supercapacitor, the RS value of the battery is between 0.4779 and 0.5737 mΩ. A cylindrical Li-ion battery exhibits a semicircular shape in the impedance spectrum, due to the oxidation and reduction reactions of Li ions, and the impedance increases with a slope of 45° in the complex plane, due to the ZW generated by Li ion diffusion. However, for a pouch-type Li-ion battery, the impedance spectrum exhibits a part of the semicircular shape, due to the oxidation and reduction reactions of Li ions, and the ZW generated by Li ion diffusion does not appear. In a supercapacitor, the oxidation and reduction reactions of ions do not appear at all, and the ZW generated by Li ion diffusion does not occur.

With the advancement in the technology of lithium-ion batteries, the popularity and awareness of rechargeable, durable, long-lasting, and lightweight ion batteries have been in the public eye for a while now. Lithium-ion (Li-ion) is not the only type of ion battery out there. Zinc-ion (Zn-ion) batteries are a heavier, but safer, cheaper, and environmentally friendly form of this battery technology that has uses when portability is not the primary objective. One such use case is large format energy storage for intermittent renewable energy such as solar and wind fields for when the sun is no longer shining, or the wind blowing. One of the disadvantages of Zn-ion batteries is that the current battery life needs to be increased to stand a chance against Li-ion batteries in terms of consumer demands. This paper describes the effect of electrode structures and charging/discharging rates on battery cycle life in coin cells. The symmetric cell study shows that higher charging/discharging rates decrease the battery's cycle life, and the polymer-coated Zn anodes improve the battery's cycle life. It is also noted that maintaining good contact with all the major components in batteries is crucial for batteries to work properly. The battery-making process carried out in the lab and the important details of battery manufacturing are described in this manuscript.

In the context of constant growth in the utilization of the Li-ion batteries, there was a great surge in the quest for electrode materials and predominant usage that lead to the retiring of Li-ion batteries. This review focuses on the recent advances in the anode and cathode materials for the next-generation Li-ion batteries. To achieve higher power and energy demands of Li-ion batteries in future energy storage applications, the selection of the electrode materials plays a crucial role. The electrode materials, such as carbon-based, semiconductor/metal, metal oxides/nitrides/phosphides/sulfides, determine appreciable properties of Li-ion batteries such as greater specific surface area, a minimal distance of diffusion, and higher conductivity. Various classifications of the anode materials such as the intercalation/de- intercalation, alloy/de-alloy, and various conversion materials are illustrated lucidly. Further, the cathode materials, such as nickel-rich LiNixCoyMnzO2 (NCM), were discussed. NCM members such as NCM 333, NCM 523 that enabled to advance for NCM622 and NCM81are reported. The nanostructured materials bridged the gap in the realization of next-generation Li-ion batteries. Li-ion batteries’ electrode nanostructure synthesis, performance, and reaction mechanisms were considered with great concern. The serious effects of Li-ion batteries disposal need to be cut significantly to reduce the detrimental effect on the environment. Hence, the recycling of spent Li-ion batteries has gained much attention in recent years. Various recycling techniques and their effect on the electroactive materials are illustrated. The key areas covered in this review are anode and cathode materials and recent advances along with their recycling techniques. In light of crucial points covered in this review, it constitutes a suitable reference for engineers, researchers, and designers in energy storage applications.

Recently, two-dimensional (2D) materials have been rapidly developed and they provided a wide application on the anode of the batteries, reducing the adverse effect of traditional ion batteries including low capacity, short cycle life, low charging rate and poor safety mainly coming from the use of graphite anode. The current report investigates the anode performances of AlSi, a new 2D material exfoliated from NaAlSi, for Li ion batterys (LIBs) through density functional theory (DFT) calculations and gives quantitative discussions on the Li ion valences, binding energies and open-circuit voltages of 2D AlSi anode. The results indicate that 2D AlSi performs great as a novel anode due to the moderate adhesion to Li and low barrier for ion diffusion. Furthermore, our research results illustrate a broad application prospect on the new anode inventions as well as reducing useless consumption on the batteries by the practice of AlSi anode.

Li-ion battery is a very promising market. Researchers and scientists are trying to improve further the function of all Li-ion batteries on the account that they still cannot meet the customers' requirements and may not be as competitive as the internal combustion engine on traveling distances. The Nanotechnology application of Li-ion battery electrodes affects the general performance such as capacity, energy density, charging and discharging speed, etc. At the atomic scale, the pulverization problem caused by lithiation also limits the growth of batteries. Nanotechnology may be one of the solutions because the strain the material can sustain at the nanoscale is extremely large. The working mechanism of Li-ion helps to have an overall understanding of how batteries work. Replacing graphite with silicon can greatly enhance the battery's performance, but there are still some problems with replacing the electrode material. There are three different types of applications of nanotechnologies that can solve the problems like pulverization: 0D nanoparticles, 1D nanowires, and 2D nanofilms. Nanotechnology is no longer at a laboratory scale and has taken part in the mass production industry.

This talk will describe the physics of driven nucleation and growth in battery materials. The resulting nonequilibrium pattern formation may be either reaction-limited or transport limited. Examples of the former include driven phase separation in Li-ion batteries, electrodeposition in Li-air batteries, and Li plating in Li-ion batteries, controlled by electro-autocatalysis and competing electrochemical reactions. Examples of the latter include stable electrodeposition in Li-metal batteries with charged porous separators, controlled by deionization shock waves.

Rechargeable Lithium ion batteries are widely used as portable power source in communication and computer technology, prospective uses include medical implantable devices and electric vehicles. The safety and cycle life of Li ion batteries is improved over that of batteries containing metallic lithium anodes because the insertion of Li between the crystal layers of both electrodes was proved to be safer than the electroplating of Li onto a metallic Lithium anode. in Li-ion batteries, the charge transport is governed by the oscillation of Li ions between anode and cathode. They are sometimes called “rocking-chair“ batteries. The most common materials for these batteries are lithiated carbons for anodes, and transition metal oxides (LixCoO2) as cathodes.LixCoO2 has an ordered rhombohedral Rm structure consisting of alternating layers of Co-O-Li-O-Co. The capacity and energy density of the batteries is limited by the amount of Li that can be stored in the anode and cathode materials.

Li-ion batteries are one of the most popular energy storage devices widely applied to various kinds of equipment, such as mobile phones, medical and military equipment, etc. Therefore, due to its numerous advantages, especially on the NMC type, there is a predictable yearly increase in Li-ion batteries' demand. However, even though it is rechargeable, Li-ion batteries also have a usage time limit, thereby increasing the amount of waste disposed of in the environment. Therefore, this study aims to determine the optimum conditions and the potential and challenges from the waste Li-ion battery recycling process, which consists of pretreatment, metal extraction, and product preparation. Data were obtained by studying the literature related to Li-ion battery waste's recycling process, which was then compiled into a review. The results showed that the most optimum recycling process of Li-ion batteries consists of metal extraction by a leaching process that utilizes H2SO4 and H2O2 as leaching and reducing agents, respectively. Furthermore, it was proceeding with the manufacturing of a new Li-ion battery.

Lithium-Ion battery cells and automotive battery systems are constantly improving as a result of the rising popularity of electric vehicles. With higher energy densities of the cells, the risks in case of failure rise as well. In the worst case, a fast exothermic reaction known as thermal runaway can occur. During thermal runaway, the cell can emit around 66% of its mass as gas and particles. An experimental setup was designed and showed that the gas-particle-vent of a cell going through thermal runaway can cause electric breakthroughs. These breakthroughs could start electric arcing in the battery system, which could lead to additional damages such as burning through the casing or igniting the vent gas, making the damage more severe and difficult to control. Uncontrollable battery fires must be prevented. The emitted gas was analyzed and the ejected particles were examined to discuss the potential causes of the breakthroughs.

Among many types of batteries, Li-ion and Li-S batteries have been of great interest because of their high energy density, low self-discharge, and non-memory effect, among other aspects. Emerging applications require batteries with higher performance factors, such as capacity and cycling life, which have motivated many research efforts on constructing high-performance anode and cathode materials. Herein, recent research about cathode materials are particularly focused on. Low electron and ion conductivities and poor electrode stability remain great challenges. Three-dimensional (3D) porous nanostructures commonly exhibit unique properties, such as good Li+ ion diffusion, short electron transfer pathway, robust mechanical strength, and sufficient space for volume change accommodation during charge/discharge, which make them promising for high-performance cathodes in batteries. A comprehensive summary about some cutting-edge investigations of Li-ion and Li-S battery cathodes is presented. As demonstrative examples, LiCoO2, LiMn2O4, LiFePO4, V2O5, and LiNi1−x−yCoxMnyO2 in pristine and modified forms with a 3D porous structure for Li-ion batteries are introduced, with a particular focus on their preparation methods. Additionally, S loaded on 3D scaffolds for Li-S batteries is discussed. In addition, the main challenges and potential directions for next generation cathodes have been indicated, which would be beneficial to researchers and engineers developing high-performance electrodes for advanced secondary batteries.

Lithium-ion (Li-ion) batteries are currently considered as vital components for advances in mobile technologies such as those in communications and transport. Nonetheless, Li-ion batteries suffer from temperature rises which sometimes lead to operational damages or may even cause fire. An appropriate solution to control the temperature changes during the operation of Li-ion batteries is to embed batteries inside a paraffin matrix to absorb and dissipate heat. In the present work, we aimed to investigate the possibility of making paraffin nanocomposites for better heat management of a Li-ion battery pack. To fulfill this aim, heat generation during a battery charging/discharging cycles was simulated using Newman’s well established electrochemical pseudo-2D model. We couple this model to a 3D heat transfer model to predict the temperature evolution during the battery operation. In the later model, we considered different paraffin nanocomposites structures made by the addition of graphene, carbon nanotubes, and fullerene by assuming the same thermal conductivity for all fillers. This way, our results mainly correlate with the geometry of the fillers. Our results assess the degree of enhancement in heat dissipation of Li-ion batteries through the use of paraffin nanocomposites. Our results may be used as a guide for experimental set-ups to improve the heat management of Li-ion batteries.

Metallic lithium (Li) anode batteries have attracted considerable attention due to their high energy density value. However, metallic Li is highly reactive and flammable, which makes Li anode batteries difficult to develop. In this work, for the first time, we report the synthesis of metallic Li-embedded carbon nanocomposites for easy and safe handling by a scalable ion beam-based method. We found that vertically standing conical Li-C nanocomposite (Li-C NC), sometimes with a nanofiber on top, can be grown on a graphite foil commonly used for the anodes of lithium-ion batteries. Metallic Li embedded inside the carbon matrix was found to be highly stable under ambient conditions, making transmission electron microscopy (TEM) characterization possible without any sophisticated inert gas-based sample fabrication apparatus. The developed ion beam-based fabrication technique was also extendable to the synthesis of stable Li-C NC films under ambient conditions. In fact, no significant loss of crystallinity or change in morphology of the Li-C film was observed when subjected to heating at 300 °C for 10 min. Thus, these ion-induced Li-C nanocomposites are concluded to be interesting as electrode materials for future Li-air batteries.

The energy density, safety, and cycle life of batteries are critical for electric vehicles (EV), electric aviation, and renewable energy storage. However, current Li-ion batteries still cannot simultaneously meet all the requirements for these applications. We developed non-flammable fluorinated organic electrolytes, aqueous electrolytes, and solid-state electrolytes to form nano-scaled solid electrolyte interphase, which enhanced the energy density, safety, and cycle life of Li batteries. The electrolyte design principle for high-capacity anodes and high-voltage cathodes will be discussed.

Lithium-ion (Li-ion) batteries as an energy storage device have drawn significant attention due to increasing demand especially in transportation, mobile, and renewable energy applications. Despite their wide utilization, the improvement of Li-ion batteries’ performance, including the enhancement of energy density, stability, and safety, remains a big challenge to overcome. Carbon nanostructures (1D, 2D, 3D) show potential as the anode materials for Li-ion batteries which possess high stability and Li-ion conductivity, yet they offer low capacity. Contrarily, metalloids and transition metal oxides materials, which show high capacity, suffer low Li-ion conductivity and exhibit volume expansion during charge/discharge. Combining these materials with carbon nanostructures to create carbon-based nanocomposites as the anode materials for Li-ion batteries is considered one of the most lucrative strategies to achieve improved performance. These composites form high stability, high conductivity, and high-capacity anode materials. Furthermore, the addition of heteroatoms to carbon nanostructures also significantly increases capacity. Herein, we intensively discuss several categories of carbon-based nanocomposites and the effect on their properties as well as performance (initial charge/discharge capacity, cycling performance). In addition, several future prospects and challenges are addressed.

Standalone microgrids with photovoltaic (PV) solutions could be a promising solution for powering up off-grid communities. However, this type of application requires the use of energy storage systems (ESS) to manage the intermittency of PV production. The most commonly used ESSs are lithium-ion batteries (Li-ion), but this technology has a low lifespan, mostly caused by the imposed stress. To reduce the stress on Li-ion batteries and extend their lifespan, hybrid energy storage systems (HESS) began to emerge. Although the utilization of HESSs has demonstrated great potential to make up for the limitations of Li-ion batteries, a proper power management strategy is key to achieving the HESS objectives and ensuring a harmonized system operation. This paper proposes a novel power management strategy based on an artificial neural network for a standalone PV system with Li-ion batteries and super-capacitors (SC) HESS. A typical standalone PV system is used to demonstrate and validate the performance of the proposed power management strategy. To demonstrate its effectiveness, computational simulations with short and long duration were performed. The results show a minimization in Li-ion battery dynamic stress and peak current, leading to an increased lifespan of Li-ion batteries. Moreover, the proposed power management strategy increases the level of SC utilization in comparison with other well-established strategies in the literature.

Electric vehicles (EVs) are becoming widely used for its low energy consumption and low pollution. An accurate estimation of available capacity for Li-ion batteries has an important utility significance to optimize its performance in the applications of EVs. The Peukert equation is applied to estimate the available capacity of batteries. However, the fact that the available capacity of Li-ion batteries is dependent on battery temperatures can result in errors while using the Peukert equation. To address this problem, this paper proposes an extended Peukert equation to include temperature effect. This method considers battery temperature as an input variable into the Peukert equation. Experiments based on Li-ion batteries are carried out under various current and temperatures. The comparison of the estimated and the actual available capacity indicates that the proposed algorithm can provide a reliable and accurate estimation of the available capacity for Li-ion batteries.

In the late 1960s, the establishment of Prigogine’s dissipative structure theory laid the foundation for the (electro)chemical oscillation phenomenon, which has been widely investigated in some electrochemical reactions, such as electro-catalysis and electro-deposition, while the electrochemical oscillation of Li-ion batteries has just been discovered in spinel Li4Ti5O12 a few years before. In this work, spinel LiCrTiO4 samples were synthesized by using a high-temperature solid-state method, characterized with SEM (Scanning electron microscope), XRD (X-ray diffraction), Raman and XPS (X-ray photoelectron spectroscopy) measurements, and electrochemically tested in Li-ion batteries to study the electrochemical oscillation. When sintering in a powder form at a temperature between 800 and 900 °C, we achieved the electrochemical oscillation of spinel LiCrTiO4 during charging, and it is suppressed in the non-stoichiometric LiCrTiO4 samples, especially for reducing the Li content or increasing the Cr content. Therefore, this work developed another two-phase material as the powder-sintered LiCrTiO4 exhibiting the electrochemical oscillation in Li-ion batteries, which would inspire us to explore more two-phase electrode materials in Li-ion batteries, Na-ion batteries, etc.

With the increasing proportion of Li-ion batteries in energy structures, studies on the estimation of the state of charge (SOC) of Li-ion batteries, which can effectively ensure the safety and stability of Li-ion batteries, have gained much attention. In this paper, a new data-driven method named the probabilistic threshold compensation fuzzy neural network (PTCFNN) is proposed to estimate the SOC of Li-ion batteries. Compared with other traditional methods that need to build complex battery models, the PTCFNN only needs data learning to obtain nonlinear mapping relationships inside Li-ion batteries. In order to avoid the local optimal value problem of traditional BP neural networks and the fixed reasoning mechanism of traditional fuzzy neural networks, the PTCFNN combines the advantages of a probabilistic fuzzy neural network and a compensation fuzzy neural network so as to improve the learning convergence speed and optimize the fuzzy reasoning mechanism. Finally, in order to verify the estimation performance of the PTCFNN, a 18650-20R Li-ion battery was used to carry out the estimation test. The results show that the mean absolute error and mean square error are very small under the conditions of a low-current test and dynamic-current test, and the overall estimation error is less than 1%, which further indicates that this method has good estimation ability.

Solid-state Li-ion batteries are emerging as promising next-generation energy storage devices, but new solid-state Li-ion conductors or electrolytes, a critical component of such devices, are highly demanded to meet the conductivity and stability requirements. In this study, one of the cost-effective and stable silicate-based solid Li-ion conductors, β-eucryptite LiAlSiO4, was studied via ab initio molecular dynamics simulations. The Si/Al ratio from 0 to 7 corresponding to x in Li1+ xAl1+ xSi1- xO4 from 1 (Li-rich) to −0.75 (Li-poor) was adjusted to investigate its impact on Li-ion diffusion. The results show that the Li-ion diffusion barrier can be greatly decreased from 0.61 eV in β-eucryptite LiAlSiO4 ( x = 0) to 0.20 eV in Li0.5Al0.5Si1.5O4 ( x = −0.5; Si/Al = 3) and 0.24 eV in Li1.25Al1.25Si0.75O4 ( x = 0.25; Si/Al = 0.6). The predicted Li-ion conductivity is 6.976 mS/cm in Li0.5Al0.5Si1.5O4 and 3.773 mS/cm in Li1.25Al1.25Si0.75O4 at 25 °C, both allowing room-temperature operation of solid-state batteries. The modulation of Li–Li correlation at these two distinctive Si/Al ratios results in significantly lower diffusion barrier and higher Li-ion conductivity than those of the parent composition. Our work facilitates the design of low-cost silicate-based Li-ion conductors with high Li conductivity.

Li-ion batteries are considered prospective candidates for storage systems because of their high energy density and long cycling life. However, the use of organic electrolytes increases the risk of explosion and fire. Hence, all-solid-state Li-ion batteries have attracted considerable attention because the use of solid electrolytes avoids the combustion of electrolytes and explosions, and enhances the performance of batteries. Garnet-type oxides are commonly used solid electrolytes. The common Ta-doped Li7La3Zr2O12 can react easily with CO2 and H2O in air, and its ionic conductivity decays after contact with air. In this study, a novel garnet-type, high-entropy oxide, Li6.4La3Zr0.4Ta0.4Nb0.4Y0.6W0.2O12 (LLZTNYWO), is successfully synthesized as a solid electrolyte for Li-ion batteries,using a conventional solid-state method. Ta, Nb, Y, and W are used as substitutes for Zr, which significantly increase conductivity, have high stability in air, and a lower sintering temperature. LLZTNYWO achieves higher Li-ion conductivity at 1.16 × 10−4 S cm−1 compared to mono-doped Li6.6La3Zr1.6Ta0.4O12 (6.57 × 10−5 S cm−1), Li6.6La3Zr1.6Nb0.4O12 (2.19 × 10−5 S cm−1), and Li6.2La3Zr1.6W0.4O12 (1.16 × 10−4 S cm−1). Additionally, it exhibits higher ionic conductivity compared to equimolar Li5.8La3Zr0.4Ta0.4Nb0.4Y0.4W0.4O12 (1.95 × 10−5 S cm−1). The Li-ion conductivity of LLZTNYWO remains constant for 30 days in the atmosphere without decay, thereby revealing its excellent air stability. Furthermore, LLZTNYWO exhibits a remarkable electrochemical window of up to 6 V vs Li/Li+ and excellent electrochemical stability against Li metal after cycling at 0.1 mA·cm−2 for 2 h, which indicates that it is a promising solid electrolyte for Li-ion batteries.

Streszczenie:

Li-ion batteries (LiBs) are widely adopted in electric vehicles (EVs) owing to their superior properties, such as high energy density, low discharge rate, long lifespan, and lightweight construction. Since the battery pack is the sole energy source for an EV, its performance is critical for optimal vehicle operation. However, the battery's calendar life, cycle life, and overall performance are significantly affected by temperature variations. The Li-ion batteries used in EVs may encounter challenging working conditions, leading to thermal problems such as significant capacity and power loss. In contrast, thermal runaways can occur at temperatures above a specific threshold, leading to severe health deterioration and sometimes catastrophic safety hazards such as fires and explosions. As the temperature significantly impacts Li-ion batteries, a battery thermal management system that can efficiently dissipate heat is crucial to ensure the battery's optimal performance and longevity. Hence, it is crucial to develop accurate algorithms for battery thermal management systems to precisely and dynamically estimate the temperature dynamics of the batteries integrated within the battery pack. While experimental data can be used to estimate battery temperatures, the dynamic and diverse operating conditions of electric vehicles (EVs) present a significant challenge. Therefore, accurately predicting thermal response within batteries is critical. Various thermal models have been developed to predict the thermal behavior of batteries and quantify the amount of heat generated. The simplified thermal model only considers joule heating and reversible entropic heating. However, more accurate physics-based models consider reversible heat caused by the side reactions, heat generated by mass transport loss, and even mixing-induced heat. The amount of heat generated inside a Li-ion battery is determined by its equivalent internal resistance, open circuit voltage, and entropy change, which are in turn influenced by temperature and depth of discharge (DoD). To the best of the authors' knowledge, previous research on the heat generation of Li-ion batteries has been limited in some respects. Specifically, there has been little investigation into the combined impact of temperature and depth of discharge (DoD) across a wide temperature range. Most studies have been conducted under ambient temperature conditions, and only a few have focused on high temperatures within a narrow range with low discharge rates. Thus, this study aims to address the research gap regarding the impact of temperature and depth of discharge (DoD) on heat generation in Li-ion batteries by analyzing these parameters using a transient battery thermal model. The research intends to improve the accuracy and precision of battery thermal behavior prediction, which has broad implications for battery-powered applications. This study aims to evaluate the impact of different resistance models on heat generation in Li-ion batteries, explicitly comparing a constant resistance model with a model that considers resistance as a function of temperature and depth of discharge (DoD). Investigating the interdependent impact of battery temperature and DoD on heat generation is crucial to create an accurate battery thermal model with high fidelity. The current study uses a two-dimensional battery thermal model to comprehensively analyze thermal behavior of a LiFePO4-20Ah Li-ion pouch cell. In this research study, heat generation in a Li-ion battery is evaluated by estimating the internal resistance and entropic change obtained from experimentation. The energy equation is then solved using the finite difference method in MATLAB to obtain the transient thermal response of the battery. The developed transient electrothermal model is validated against experimental data under varying C rates to assess the accuracy and precision of the proposed model. The simulation results show that the thermal response obtained considering the effect of temperature and DoD on heat generation shows more accurate results than the constant resistance values. The thermal behavior of a LiFePO4 pouch cell, considering constant values for heat generation, has a maximum relative error of roughly 19.99% compared to experimental data at a 4C discharge rate. While this maximum relative error was reduced to 6.29% when considering the effect of temperature and DoD on heat generation. In the constant resistance model, more significant errors can be attributed to the fact that the resistance of a Li-ion battery varies with the depth of discharge (DoD). While the initial discharge phase of the battery exhibits minimal changes in resistance values, a substantial increase in resistance occurs during the final stages of discharge. This contrasts with the actual behavior of Li-ion batteries, which demonstrate significant variations in resistance values throughout the discharge process. Thus, coupling the effects of DoD and temperature on heat generation is necessary to accurately predict the thermal behavior of Li-ion battery. Figure 1

Over the past decade, Unmanned Aerial Vehicles (UAVs) have begun to be increasingly used due to their untapped potential. Li-ion batteries are the most used to power electrically operated UAVs for their advantages, such as high energy density and the high number of operating cycles. Therefore, it is necessary to estimate the Remaining Useful Life (RUL) and the prediction of the Li-ion batteries’ capacity to prevent the UAVs’ loss of autonomy, which can cause accidents or material losses. In this paper, the authors propose a method of prediction of the RUL for Li-ion batteries using a data-driven approach. To maximize the performance of the process, the performance of three machine learning models, Support Vector Machine for Regression (SVMR), Multiple Linear Regression (MLR), and Random Forest (RF), were compared to estimate the RUL of Li-ion batteries. The method can be implemented within UAVs’ Predictive Maintenance (PdM) systems.

Li-ion batteries (LIBs) and Na-ion batteries (SIBs) are deemed green and efficient electrochemical energy storage and generation devices; meanwhile, acquiring a competent anode remains a serious challenge. Herein, the density-functional theory (DFT) was employed to investigate the performance of V4C3 MXene as an anode for LIBs and SIBs. The results predict the outstanding electrical conductivity when Li/Na is loaded on V4C3. Both Li2xV4C3 and Na2xV4C3 (x = 0.125, 0.5, 1, 1.5, and 2) showed expected low-average open-circuit voltages of 0.38 V and 0.14 V, respectively, along with a good Li/Na storage capacity of (223 mAhg−1) and a good cycling performance. Furthermore, there was a low diffusion barrier of 0.048 eV for Li0.0625V4C3 and 0.023 eV for Na0.0625V4C3, implying the prompt intercalation/extraction of Li/Na. Based on the findings of the current study, V4C3-based materials may be utilized as an anode for Li/Na-ion batteries in future applications.

Energy storage is an important technical means to increase the consumption of renewable energy and reduce greenhouse gas emissions. Electrochemical energy storage, represented by lithium-ion batteries, has a promising developmental prospect. The performance of lithium-ion batteries continues to decline in the process of application, and the differences between batteries are increasing. Therefore, accurate estimation of the state of health (SOH) of batteries is the key to the safe and efficient operation of energy storage systems. In this paper, the electrochemical impedance spectroscopy (EIS) characteristics of Li-ion batteries under different states of charge and health were studied. Three groups of Li-ion battery impedance module values under different frequencies were selected as characteristic parameters, and the SOH estimation model of Li-ion batteries was built by using the support vector regression (SVR) algorithm. The results show that: the model with the second group of frequency-point combinations as characteristic parameters takes into account both accuracy and efficiency; the cumulative time of the characteristic frequency test and SOH evaluation of lithium-ion batteries is less than 10 s; and this technology has good engineering application value.

Our need for portable energy is increased day by day. Batteries, which are indispensable for modern life, gain more importance in the communication time. Therefore, batteries with the ability to storage a lot of energy in a short time are need. This need is met by Lithium-ion batteries. Of course, the increasing use of batteries with the formation of a fast consumer society poses a potential danger to the environment and human health.Indiscriminate release end of life batteriesto the environment causes serious metal pollution, but there are also serious economic losses due to the materials that have economic value. In this study, 12 waste battery collection points were determined within the boundaries of Namik Kemal neighborhood of Umraniye district in Istanbul, and the "end-of-life batteries" collected at these points within a three-month period were classified and their components were examined. The average composition of 110 Li-ion batteries collected during this period was determined as 20% Cu (Copper), 8% Al (Aluminum), 10% plastic, 55% battery paste (LiCoO2) and 7% others. The reusability of the metal and plastic parts obtained in the study was observed, and some spectroscopic analyzes were carried out for the reusability of the battery paste. As can be seen from the SEM-EDX analyzes supported by XRD and XRF analyzes, the morphological structure of the compound is disrupt during the application of charging and discharging many times to the Li-metal oxide compounds used as cathode material. It does not appear possible to reuse the battery paste of used (depleted) Li-ion batteries directly and/or by applying some simple operations. Multi-step chemical processes are needed to ensure the reusability of the battery paste. An economic value study was carried out for the collected Li-ion batteries and the importance of collecting the waste batteries and bringing them into the economy was emphasized.

MnSi2N4 possesses low diffusion barrier for Li (0.32 eV) and Na (0.19 eV), as well as high storage capacity as an anode for Li (320 mAh g−1) and Na (160 mAh g−1) ion batteries, respectively. These properties, including excellent electronic conductivity, low diffusion barrier, and high storage capacity, enable MnSi2N4 a promising anode for Li and Na ion batteries.
