Abstract:
Lithium metal anodes have been pursued for decades as a way to significantly increase the energy density of lithium-ion batteries. However, safety risks caused by flammable liquid electrolytes and short circuits due to lithium dendrite formation during cell cycling have so far prevented the use of lithium metal in commercial batteries. Solid polymer electrolytes (SPEs) offer a potential solution if their mechanical properties and ionic conductivity can be simultaneously engineered. Here, we introduce a family of SPEs that are scalable and easy to prepare with a photopolymerization process, synthesized from amphiphilic acrylic polymer conetworks based on poly(ethylene glycol), 2-hydroxy-ethylacrylate, norbornyl acrylate, and either lithium bis (trifluoromethanesulfonyl) imide (LiTFSI) or a single-ion polymethacrylate as lithium-ion source. Several conetworks were synthesized and cycled, and their ionic conductivity, mechanical properties, and lithium transference number were characterized. A single-ion-conducting polymer electrolyte shows the best compromise between the different properties and extends the calendar life of the cell.

Abstract:
Lithium-sulfur batteries (LSBs) have garnered interest recently due to their 8-fold increase in theoretical capacity compared to state-of-the-art Li-ion batteries (LIBs), the affordability of sulfur at $100/ton, and the low environmental impact of sulfur. However, just like LIBs, LSBs suffer from anode instability due to dendrite formation and an unstable solid electrolyte interface (SEI). In this work, we address anode stability via a facile, polymer and lithium salt interfacial layer. Stable SEI formation was achieved by using a fluorinated polymer and lithium salt. A conventional Celgard separator was used for mechanical support and the polymer:salt ratio was tuned. To confirm the effectiveness of the interfacial layer for anode stability, it was used as a standalone gel polymer electrolyte in a Li-Li symmetric cell. It showed remarkable stability beyond 700 hours at an energy density of 1 mA cm-2 and capacity of 1 mAh cm-2, with a steady polarization voltage of 16mV. By comparison, a Li-Li symmetric cell with a Celgard separator began to show increasing polarization voltage after just 100 hours, with a polarization voltage that gradually increased to beyond 500mV (Figure 1). This stability was achieved by a robust SEI layer that contained LiF and Li2O, hindering the formation of the dead lithium layer. The presence of these compounds was confirmed by post-mortem X-ray photoelectron spectroscopy. Dendrite formation was also physically inhibited by the presence of the polymer matrix that had a uniform morphology and pore diameter around 1 μm. Additionally, using this interfacial layer in a lithium-sulfur coin cell provided a capacity of 866 mAh g-1 at 200 cycles, a 26% improvement over lithium-sulfur cells without the interfacial layer.

Abstract:
The ongoing electrification of the transportation sector is triggering a continuous search for batteries with higher energy density. One approach to achieve this goal is the transition to lithium-metal anodes. However, the practical implementation brings about severe safety issues such as the dendritic deposition and growth of metallic lithium and the consequent risk of accidental short circuiting of the cell, resulting in a thermal runaway.1 Solid-state electrolytes such as polymers are considered a viable strategy to overcome this issue, especially single-ion conducting polymers, owing to the absence of the detrimental reversed cell polarization, the uniform Li+ flux, and frequently higher limiting current densities.2,3 In fact, the latter is of utmost importance for the fast charging of battery cells as well as the eventual power density. So far, however, the cycling performance at high dis-/charge rates and high current densities for battery cells comprising a polymer electrolyte remained little investigated and commonly non-satisfactory. Here, we report the development of a polysiloxane-based single-ion conducting polymer electrolyte (PSiOM) with a Li+ conductivity exceeding 10−4 S cm−1 at ambient temperature and excellent stability towards both lithium metal and high-energy LiNi0.8Co0.1Mn0.1O2 (NMC811) as the active material for the positive electrode. This new polymer electrolyte enables dendrite-free lithium deposition, thanks to the formation of a suitable electrode|electrolyte interface and interphase and the uniform Li+ flux. Moreover, PSiOM allows for an outstanding capacity retention of, e.g., 90% at 1C and 86% at 2C after 300 cycles and rapid charging and discharging at C rates as high as 5C. It is important to note that we used reasonable active material mass loadings for these tests (>7 mg cm-2), which means that the current densities applied were up to 7.20 mA cm−2 at 40 °C and 2.88 mA cm−2 at 20 °C. To the best of our knowledge, these current densities are among the highest reported so far for polymer-based electrolytes. References (1) Kalhoff, J.; Eshetu, G. G.; Bresser, D.; Passerini, S.

Abstract:
Lithium-sulfur batteries are next-generation battery systems with low cost and high specific energy. However, it is necessary to solve several deficiencies of these batteries such as shuttle effect, and gel polymer electrolyte is a great candidate. These perspective materials can be used as a replacement for liquid electrolytes, and at the same time, they can help to solve the problems of lithium-sulfur batteries. In this work, gel polymer electrolyte (GPE) based on methyl methacrylate was prepared by cross-linking strategy. As cross-link ethylene glycol dimethacrylate (EDMA) was used. Prepared gel with a high electric conductivity was testing in the lithium-sulfur cell (Li/GPE/S). The electrochemical performance of the cell was studied.

Abstract:
Rechargeable solid-state lithium metal batteries are highly promising systems beyond lithium-ion technology, potentially affording high gravimetric and volumetric energy densities. Despite substantial progress in this field, significant challenges remain, including interfacial changes upon cell operation and achievement of reversible lithium inventory. Here, polymer electrolytes may offer flexible solutions and operational safety, providing compromises among conflicting demands of mechanical robustness and sufficient ionic conductivity, though advancements and tailored design of future polymer materials of functional layers and cell designs require input from insights into interfacial processes, characteristic charge transfer rates and associated resistances at electrode|electrolyte interfaces, respectively. In this work, electrochemical impedance spectroscopy (EIS) is therefore carefully exploited for the analysis of relevant charge transfer processes in case of introduced polymer electrolytes[1], invoking a distribution of relaxation times (DRT) approach. The obtained complex permittivity and conductivity of the materials upon variation of temperature as well as explicit modification of the thin lithium metal electrodes with artificial polymer layers yield characteristic data of the evolution of interfacial resistances and the corresponding charge transfer reactions, in this way demonstrating the significant diagnostic strength of EIS/DRT analysis for future developments. In addition, operando EIS/DRT analysis is done upon plating of lithium metal, complemented by 7Li solid-state NMR spectra acquired at various states during lithium deposition, thereby revealing occurring species and their microstructures based on the 7Li NMR chemical shifts. In summary, EIS/DRT analysis is utilized as powerful diagnostic technique, highlighting how to exploit observable trends of characteristic parameters at electrode|electrolyte interfaces for future design of polymer-based materials as well as high performance cell concepts.

Abstract:
Gel polymer electrolyte (GPE) is widely considered as a promising safe lithium-ion battery material compared to conventional organic liquid electrolyte, which is linked to a greater risk of corrosive liquid leakage, spontaneous combustion, and explosion. GPE contains polymers, lithium salts, and liquid electrolyte, and inorganic nanoparticles are often used as fillers to improve electrochemical performance. However, such composite polymer electrolytes are usually prepared by means of blending, which can impact on the compatibility between the polymer and filler. In this study, the hybrid copolymer poly (organic palygorskite-co-methyl methacrylate) (poly(OPal-MMA)) is synthesized using organic palygorskite (OPal) and MMA as raw materials. The poly(OPal-MMA) gel electrolyte exhibits an ionic conductivity of 2.94 × 10−3 S/cm at 30 °C. The Li/poly(OPal-MMA) electrolyte/LiFePO4 cell shows a wide electrochemical window (approximately 4.7 V), high discharge capacity (146.36 mAh/g), and a low capacity-decay rate (0.02%/cycle).

Abstract:
Fibrous membranes are promising separators for high-performance lithium ion battery because of their high porosity and superior electrolyte uptake. In this paper, the fabrication of hybrid gel polymer electrolyte (HGPE) by introducing SnO2 nanoparticles in poly(vinylidine fluoride) by electrospinning technique and soaking the electrospun nanofibrous membranes in 1 M LiPF6 in ethylene carbonate (EC)/diethyl carbonate (DEC) (1:1, v/v). The as-prepared electrospun HGPE with SnO2 nanofiller was characterized by scanning electron microscopy. The influence of SnO2 on the structure of polymer membrane, physical, and electrochemical properties is systematically investigated. HGPE shows significant high ionic conductivity 4.6 × 10[Formula: see text] S/cm at room-temperature and better cell performance such as discharge C-rate capability and cycle performance. The hybrid gel polymer nanofibrous membrane favors high uptake of lithium electrolyte so that electrolyte leakage is reduced. The gel polymer electrolyte with SnO2 filler was used for the fabrication of Li/PVdF-SnO2/LiFePO4 coin cell. The fabricated cell was evaluated at a current density of 0.2 C-rate and delivered stable and excellent cycle performance. This study revealed that the prepared HGPE can be employed as potential electrolyte for lithium ion batteries.

Abstract:
The Direct Methanol Fuel Cell (DMFC) has been considered as one of the competitive alternatives for battery technology as it has much higher energy density, faster recharging and does not require complicated control systems like a fuel reformer or compressed gas tank as needed by a hydrogen fuel cell. However, current DMFC technology suffers from the low power density caused by low reaction rate and undesired “methanol crossover” issues, which brings a big challenge for its application in practical systems. This thesis presents a practical design and prototype development of a DMFC/battery hybrid energy management system, which can be provided as one possible solution for the low power and cold start issues. First of all the existing fuel cell hybrid system schemes and design of the auxiliary units (BOP) are surveyed and compared. Based on the analysis above a microcontroller-based DMFC and Lithium Polymer Battery hybrid system is proposed. After that a novel “Battery-Current-Based Hybrid Control (BCBHC)” is proposed to provide active load sharing and proper battery charging and protection. The DMFC will follow the average battery current by neglecting the battery current transients and charge the battery by following the Constant-Current and Constant Voltage charging scheme when possible. A variety of battery protections, such as overcharging, overcurrent and charging current limitation, are implemented by the BCBHC and protection circuit. A detailed system design and modeling are then presented. The models are developed and simulated in PSIM. The simulation results are analyzed and showed the validity of proposed hybrid control. At the end a prototype hybrid EMS controller board has been implemented to further validate the hybrid system design. The dynamic behavior of DMFC/Battery hybrid system is examined and tested under a series of load experiments. The measured results have proved the feasibility and stability of the designed hybrid control.

Abstract:

Proton exchange membrane fuel cells and lithium polymer batteries are important as future power sources in electronic devices, vehicles and stationary applications. The development of these power sources involves finding and characterising materials that are well suited r the application.

The materials investigated in this thesis are the perfluorosulphonic ionomer NafionTM (DuPont) and metal oxides incorporated into the membrane form of this material. The ionomer is used as polymer electrolyte in proton exchange membrane fuel cells (PEMFC) and the metal oxides are used as cathode materials in lithium polymer batters (LPB).

Crystallinity in cast Nafion films can be introduced by ion beam exposure or aging. Spectroscopic investigations of the crystallinity of the ionomer indicate that the crystalline regions contain less water than amorphous regions and this could in part explain the drying out of the polymer electrolyte membrane in a PEMFC.

Spectroscopic results on the equilibrated water uptake and the state of water in thin cast ionomer films indicate that there is a full proton transfer from the sulphonic acid group in the ionomer when there is one water molecule per sulphonate group.

The LPB cathode materials, lithium manganese oxide and lithium cobalt oxide, were incorporated in situ in Nafion membranes. Other manganese oxides and cobalt oxides were incorporated in situ inside the membrane. Ion-exchange experiments from HcoO2 to LiCoO2 within the membrane were also successful.

Fourier transform infrared spectroscopy, Raman spectroscopy and X-ray diffraction were used for the characterisation of the incorporated species and the Nafion film/membrane.

Abstract:
Ce travail se situe dans le cadre de l'application des polymeres conducteurs electroniques (pce) aux batteries rechargeables. L'objectif a ete d'associer deux partenaires aux proprietes electrochimiques complementaires: un pce, la polyaniline, connue pour sa bonne tenue a la charge permanente, une autodecharge faible et une cyclabilite elevee en batterie, et un systeme electroactif base sur le couple redox disulfure/dithiolate qui presente une forte densite d'energie massique. Trois voies ont ete successivement explorees: - la preparation d'une polyaniline substituee sur le cycle par un groupement thiol. L'homopolymere n'a pu etre synthetise simplement car la forme oxydee radicalaire de la dithiodianiline s'adsorbe a la surface des electrodes ou se suroxyde. Nous avons plutot prepare un copolymere aniline-dithiodianiline par voie chimique. Malheureusement, le copoly(aniline-dithiodianiline) n'est pas conducteur et les proprietes electrochimiques des 2 partenaires ne sont ni additives, ni compatibles. - le melange en composite moleculaire pani-polydimercaptothiadiazole (polydmct): ce polydisulfure constitue une electrode reversiblement electropolymerisable qui possede une remarquable densite coulombique massique mais une mauvaise cyclabilite liee a la diffusion des especes thiolates dans l'electrolyte et passivation du metal dans les batteries lithium. Nous avons pu determine la composition optimale de chaque constituant a partir de tests en batteries lithium. La capacite maximale atteinte est 117 ah/kg sous 1 ma cm-2 mais la mauvaise cyclabilite electrochimique du polydmct n'a pas ete resolue. - la fonctionnalisation d'une polyaniline sur l'azote par un groupement carbodithioate: l'action du disulfure de carbone sur une solution de pani sous forme leucoemeraldine permet de greffer environ 80% des azotes en conservant une bonne conductivite (1 s.

Le phenomene de la passivation de l'electrode carbone-lithium utilisee comme pole negatif dans la batterie lithium-ion est d'une importance cruciale dans les caracteristiques du fonctionnement de cette electrode. Il en fixe la capacite reversible (ou utile), la duree de vie et le taux d'autodecharge. Ce travail est une contribution a la comprehension des processus chimiques et electrochimiques survenant a la surface de l'electrode au cours de l'echange du lithium avec une solution electrolytique a base d'un ou plusieurs solvant(s) organique(s) et d'un sel de lithium et conduisant a la formation d'un film de passivation. Apres une presentation bibliographique qui situe l'etude dans son contexte national et international, le travail experimental s'adresse dans un premier temps au role des parametres qui influent sur le processus de passivation tels que la nature de l'anion du sel de lithium et celle du materiau carbone ainsi que la composition de l'electrolyte. La caracterisation de ce film obtenu par des methodes chimiques ou electrochimiques utilise une large gamme de techniques : drx, meb, met, microscopie a champ proche (afm), ir-tf, rmn, esca, atg et dsc. Les techniques electrochimiques sont aussi variees : chronoamperometrie, chronopotentiometrie, impedance complexe et voltamperometrie cyclique. Les resultats obtenus sont pour la plupart originaux. Ainsi, les analyses de la composition chimique du film par esca et par ir-tf sont non seulement completes et nouvelles mais mettent en evidence pour la premiere fois le caractere polymere du film. Ce resultat devrait avoir des repercutions importantes sur l'elaboration ex situ du film pour une etude plus approfondie. L'observation du film forme sur un graphite hautement oriente par afm a permis d'obtenir les images les plus precises et les plus claires jamais publiees. L'etude electrochimique est completee par une synthese chimique du film par une methode originale. L'utilisation de ce film comme electrolyte de type plastifie a ete demontree.

Abstract:
Synthesis of hyper branched polymer (HBP) based electrolyte has been examined in this study. A real world lithium-air battery cell was fabricated using the developed HBP electrolyte, oxygen permeable air cathode and lithium metal as anode material. Detailed synthesis procedures of hyper branched polymer electrolyte and the effect of different operation conditions on the real-world lithium-air battery cell were discussed in this paper. The fabricated battery cells were tested under dry air with 0.1mA∼0.2mA discharge current to determine the effect of different operation conditions such as carbon source, electrolyte types and cathode processes. It was found that different processes affect the battery cell performance significantly. We developed optimized battery cell materials upon taking into account the effect of different processes. Several battery cells were fabricated using the same optimized anode, cathode and electrolyte materials in order to determine the battery cells performance and reproducibility. Experimental results showed that the optimized battery cells were able to discharge over 55 hours at over 2.5V. It implies that the optimized battery cell can hold charge for more than two days at over 2.5V. It was also shown that the lithium-air battery cell can be reproduced without loss of performance with the optimized battery cell materials.

Abstract:
We report improved performance of Li-ion polymer batteries through advanced gel polymer electrolytes (GPEs). Compared to solid and liquid electrolytes, GPEs are advantageous as they can be fabricated in different shapes and geometries; also ionic properties are significantly superior to that of solid and liquid electrolytes. We have synthetized GPE in form of membranes by trapping ethylene carbonate and propylene carbonate in a composite of polyvinylidene fluoride and N-methylpyrrolidinore. By applying phase-transfer method, we synthetized membranes with micro-pores, which led to higher ionic conductivity. The proposed membrane is to be modified further to have higher capacity, stronger mechanical properties, and lower internal resistance. In order to meet those requirements, we have doped the samples with gold nanoparticles (AuNPs) to form nanoparticle-polymer composites with tunable porosity and conductivity. Membranes doped with nanoparticles are expected to have higher porosity, which leads to higher ion mobility; and improved electrical conductivity. Four-point-probe measurement technique was used to measure the sheet resistance of the membranes. Morphology of the membranes was studied using electron and optical microscopies. Cyclic voltammetry and potentiostatic impedance spectroscopy were performed to characterize electrochemical behavior of the samples as a function of weight percentage of embedded AuNPs.

Abstract:
The aim of our work is to design, fabricate and characterize multifunctional structure-power composites for marine applications such as in unmanned underwater vehicles. Three types of structure-power (or structure-battery (SB)) specimens were fabricated using fiber-reinforced polymers and closed-cell foam as the structural components, and commercial-off-the-shelf lithium-polymer cells as the power-plus-structure component. This paper details the mechanical and electrical characterization of the S-B composites while a companion paper deals with the design and fabrication issues. The three multifunctional designs are: integrated SB laminate with lithium-polymer pouch cells embedded on one side, SB sandwich with cells embedded within a closed-cell polymeric foam along the neutral axis, and a SB modular stiffener that can be attached and removed from a host-structure. Unifunctional composites (i.e. without embedded cells) were also fabricated for comparison with the multifunctional composites. The embedded cells show identical charge-discharge electrical performance as their un-embedded counterparts, thus, indicating that the composite fabrication procedures did not adversely affect their electrical performance. Ragone curves (energy density vs. power density) of the S-B composites show that the targeted energy density of 50 Wh/L was achieved in the SB modular stiffener design. The bending stiffnesses of the integrated SB and SB modular stiffener designs were ∼7x greater than the unifunctional design while the multifunctional sandwich specimens were ∼17% stiffer than their unifunctional counterparts. Tests are currently being conducted to determine the affect of mechanical flexure (constant displacement) on embedded cell discharge and charge characteristics, and conversely, cell discharge and charge on the load and deflection during flexure.

Abstract:
The main driving force in developments of consumer electronics, such as cell phones and laptop computers, is longer run times and more functionality. In this quest for higher energy densities battery characteristics improve at a constant pace. Fuel cells seem to be the next big technology breakthrough improving energy density with a factor 3 to 10 compared to current lithium ion batteries. In particular the Direct Methanol Fuel Cell (DMFC) is an interesting opportunity because of the high energy capacity of methanol and the handling of the fuel making ‘charging’ easy, safe and fast. To get information on the different aspects that determine the boundaries of the DMFC power source, a power source for a MP3 player, the Samsung YP-Z5F, is designed. This design is based on a DMFC plus battery (DMFC hybrid) and utilizes standard available components [1]. Design of a DMFC hybrid power source in a conventional way (standard practice engineering) will not result in a smaller power source for this particular application. The design has a power and energy density lower than the currently available lithium polymer battery, mainly because of the low fuel efficiency of the cell at low temperatures, the use of commercially available but still too bulky components, and a large amount of dead space (≈34%). There are three ways to increase power and energy density of the system. First by increasing the fuel-efficiency of the cells membrane. Second by scaling down the system components to the right proportions and third by improving the systems architecture diminishing empty space. This paper presents the design of a DMFC hybrid with scaled-down components. A literature study is done on the efficiency improvements of DMFC cells. The results are presented in a CAD model and evaluated, comparing the ‘optimized design’ with ‘standard practice’ design and the current lithium-polymer battery. The energy density of the redesigned fuel-cell system is still low compared to the used lithium-polymer battery, but an improvement to the preliminary design.

Abstract:
Abstract Operating temperature has a significant impact on the performance, safety, and cycle lifetime of the lithium-ion batteries. The operating temperature of a battery is the result of the ambient temperature augmented by the heat generated by the battery. This paper presents the empirical investigation of the effect of ambient temperature on the performance of a Lithium-Nickel-Manganese-Cobalt-Oxide based cell with 3.6V nominal voltage and 20Ah capacity. The experiments are carried out in an environment chamber using five controlled temperatures at −20°C, −10°C, 0°C, 20°C, and 50°C, as the ambient temperatures. In each controlled temperature test, a constant current (10A, 20A, and 40A) continuously discharge the cell to a cut-off 2.5V. The cell discharging voltages and usable capacities are the battery performance indicators. The experimental tests show that discharging voltage at 50% DOD and the total discharging time to reach 2.5V (usable capacity) increase as the ambient temperature increases. The modeling and simulation of a battery cell temperature model is built in the Simulink platform. The correlations show that simulated and experimental discharging curves match well in the 0–80% DOD range and the discrepancy is under 7%. The developed simulation model could provide thermal management guidelines for lithium-ion polymer battery applications in 12 voltage SLI, start-stop, and 48 voltage mild hybrid electric vehicles.

Abstract:
An intuitive and comprehensive lithium-ion polymer battery cell model is developed in the Simulink environment. The developed model has capability of transient function in the Thevenin-based model, AC-equivalent function in the impedance-based model, and runtime prediction in the runtime-based model. Several model parameters are determined through five experimental discharging currents (6.67A, 10A, 20A, 30A, and 40A). The model is correlated and validated with other three continuous discharging currents (4A, 15A, and 50A) and two pulse discharges (20A and 30A). The validation indicates a less than 7% discrepancy between model simulation and experiment. The model is currently effective for lithium-metal-oxides polymer battery cell with capacity between 18Ah and 22Ah (20Ah +/− 10%). For other capacity battery cell, the parameters of series resistors need to be adjusted in the model. These parameters can be determined using three to five continuous constant current discharging tests. It is intended to make the developed cell model scalable and accurate in a wider ranges of battery specifications. Expending the developed cell model to a 12 voltage Starting-Lighting-Ignition (SLI) battery used in the start-stop or 48 voltage battery pack for mild hybrid electric vehicle is an example.
