Abstract:
Separators present the crucial functions of separating the positive and negative electrodes due to the free flow of lithium ions through the liquid electrolyte that fills in their open pore. Separators for liquid electrolyte Lithium-ion batteries can be classified into porous polymeric membranes, nonwoven mats, and cellulose separators. When a lithium-ion battery is being overcharged, it releases the heat and results in the inner-short. The polyethylene (PE) separators used here had shut down at around 135°C to cool the exothermal batteries. To enhance the meltdown temperature of the separator, a PE separator was coated with polymers synthesized from various ethylene glycol dimethacrylate monomers. At the same time, nonwoven mats have the potential to be low cost and thermally stable separators. Furthermore, the lithium-ion phosphate/lithium half cell using cellulose separator exhibited stable charge-discharge capability even at 120 °C. This paper presents an overview of the PE and PP membranes of lithium-ion battery separators, discusses how to solve their disadvantages, and reviews the cellulose-based materials developed for potential application in the lithium-ion battery.

Abstract:
Lithium battery separators play a critical role in the performance and safety of lithium batteries. In this work, four kinds of polymer particle adhesives (G1–G4) for lithium battery separators were synthesized via dispersion polymerization, using styrene, butyl acrylate and acrylonitrile as monomers. The particle size/size distributions, particle morphologies and glass transition temperatures (Tg) of polymer particle adhesives were explored using laser particle size analysis, scanning electron microscopy (SEM) and differential scanning calorimetry (DSC), respectively. The adhesion strengths between the battery separators and the poles piece were examined using a tensile machine. The prepared polymer particle adhesive with a uniform distribution of particle size was obtained when the mass ratio of ethanol to water reached 85:15. Compared with the other three polymer particle adhesives, the prepared G3 coated on the surface of the battery separator exhibited a stronger adhesion with the battery pole piece. In addition, the Land battery test system was applied to examine the electrochemical performance of the lithium battery assembled with the battery separator with the prepared polymer particle adhesives. The results suggest that the electrochemical performance of the lithium battery assembled with the battery separator with polymer particle adhesive G3 is the best among the four counterparts.

Abstract:
Separators are key materials to ensure the safety of lithium-ion batteries and improve their performance. Currently, commercial lithium-ion battery separators are mainly polyolefin organic diaphragms, but their temperature instability leads to battery short circuit and fire risk. A flexible SiO2 nanofiber membrane combined with a poly(vinylidene fluoride-hexafluoropropylene) (PVDF-HFP) nanofiber membrane is prepared by an electrospinning method. The mechanical strength of the SiO2/PVDF-HFP composite nanofiber membrane (SPF) is twice as high as the pure SiO2 nanofiber membrane and at 200°C, there are almost no dimensional changes of the SPF separators. Compared to commercial polyethylene (PE) separators, SPF shows excellent thermal stability and large-area closed cells at 180°C when used in lithium-ion battery separators. The porosity of SPF is 89.7%, which is more than twice than that of an ordinary PE separator. The liquid absorption rate of SPF is much higher than an ordinary PE separator and has reached 483%. Furthermore, the cycle and rate performance of lithium-ion batteries prepared by SPF has been improved significantly. These excellent properties, as well as the potential for large-scale production of electrospinning technology, make SPF an ideal choice for high-power battery separators.

Abstract:
In recent years, the applications of lithium-ion batteries have emerged promptly owing to its widespread use in portable electronics and electric vehicles. Nevertheless, the safety of the battery systems has always been a global concern for the end-users. The separator is an indispensable part of lithium-ion batteries since it functions as a physical barrier for the electrode as well as an electrolyte reservoir for ionic transport. The properties of separators have direct influences on the performance of lithium-ion batteries, therefore the separators play an important role in the battery safety issue. With the rapid developments of applied materials, there have been extensive efforts to utilize these new materials as battery separators with enhanced electrical, fire, and explosion prevention performances. In this review, we aim to deliver an overview of recent advancements in numerical models on battery separators. Moreover, we summarize the physical properties of separators and benchmark selective key performance indicators. A broad picture of recent simulation studies on separators is given and a brief outlook for the future directions is also proposed.

Abstract:
Lithium (Li) metal batteries (LMBs) have received extensive research attention in recent years because of their high energy density. However, uncontrollable Li dendrite growth deteriorates the battery life and brings about severe safety hazards. The rational design of battery separators is an effective approach to regulate uniform Li metal deposition towards boosted cycle life and safety of LMBs. Herein, we review the recent research progress concerning this issue, including mechanically strengthened separator fabrication, functional separator construction towards regulated Li ion deposition, and flame-retardant separator design. Moreover, the key issues and prospects of optimal design of separators are clarified for future development. This minireview is expected to bring new insight into developing advanced separators for long-life and safe LMBs.

Abstract:
Li dendrite growth, which causes potential internal short circuit and reduces battery cycle life, is the main hazard to lithium metal batteries. Separators have the potential to suppress dendrite growth by regulating Li+ distribution without increasing battery weight significantly. However, the underlying mechanism is still not fully understood. In this paper, we apply an electrochemical phase-field model to investigate the influences of separator thickness and surface coating on dendrite growth. It is found that dendrite growth under thicker separators is relatively uniform and the average dendrite length is shorter since the ion concentration within thicker separators is more uniform. Moreover, compared to single layer separators, the electrodeposition morphology under particle-coated separators is smoother since the particles can effectively regulate Li ionic flux and homogenize Li deposition. This study provides significant guidance for designing separators that inhibit dendrites effectively.

Abstract:
Ce travail s'est concentré sur la compréhension de l'influence de la formulation et plus spécifiquement de la silice précipitée sur la résistivité électrique de séparateurs en polyéthylène destinés à des batteries au plomb. Les séparateurs de batteries en polyéthylène sont composés de silice précipitée, de polyéthylène ultra haute masse molaire (UHMWPE) et d'huile organique. La première partie de ce travail a été d'élaborer à l'échelle du laboratoire, des membranes modèles en polyéthylène. La seconde a été de comprendre l'influence de certains facteurs sur les propriétés structurales et physicochimiques des membranes. Ces facteurs sont principalement la quantité d'huile, la quantité et le grade de silice précipitée, les conditions de température lors de la cristallisation de la membrane et le mode de mise en œuvre utilisé. Les influences des quantités d'huile et de silice sur la cristallisation du polyéthylène sont méticuleusement étudiées, montrant que l'huile aide à augmenter la cristallinité finale de l'UHMWPE et que la silice joue un rôle de réservoir d'huile. Il a également été mis en évidence que la quantité ainsi que le grade de silice influencent la quantité de porosité de la membrane mouillable par l'électrolyte. La présence de silice en surface des pores est responsable de la mouillabilité de la membrane. Un paramètre empirique a donc été proposé dans le but de pouvoir quantifier l'efficacité de l'état de dispersion/distribution de la silice précipitée dans la membrane. Pour terminer, pour une formulation et un même mode de mise en œuvre, il est possible de discriminer l'efficacité des grades de silice précipitée pour l'application séparateur de batterie
This work is devoted to understand the effect of the formulation and more specifically of the precipitated silica on the resistivity of the PE-separators. The PE-separators are designed for the lead-acid batteries. PE-separators are composed of precipitated silica, ultrahigh molecular weight polyethylene (UHMW-PE) and organic oil. The first part of this work was to elaborate PE-separator models at a laboratory scale. Then, the factors impacting the structural and physico-chemicals properties of PE-separators were investigated. These factors are mainly the amounts of oil, precipitated silica, the grade of the precipitated silica, the temperature conditions of crystallization and the device used to elaborate the membrane. The influence of the amounts of oil and precipitated silica on the crystallization of the polyethylene wasthoroughly described showing that the oil helps to increase the final crystallinity of UHMWPE and that the silica plays a role of oil reservoir. Moreover, it was shown that the amount and the grade of precipitated silica have an influence on the wettable part of the porosity of the PE-separators. The coating of the pores by the precipitated silica is responsible of the wettability of the membranes by the electrolyte. Thus, an empirical parameter has been proposed in order to quantify the efficiency of the dispersion and distribution of the precipitated silica in the membrane. The more the membranes are wettable by the electrolyte the more the resistivity of the membranes is decreased. To finish, for a same amount of components and a same method of processing, it is possible to discriminate the efficiency of each grade of precipitated silica for the battery separator application

Abstract:
Lithium-ion battery (LIB) is widely utilized in many modern applications as energy sources. Numerous efforts have been dedicated to increasing electrochemical performances, but improvement on battery safety remains a visible challenge. While new electrode materials have been developed, advancement in new separator for LIB has remained relatively slow. Separator is the polymeric porous material that physically separates electrodes and allows free flow of ions through its structure. It is electrochemically inactive but essential for avoiding thermal runaway conditions. Besides its crucial functions, separator has been known as the mechanically weakest component. Structural battery is a new approach that employs multifunctional material concept to use LIB as load-bearing material to minimize the weight of the complete system and maximize the efficiency. Separator materials are required to have good thermal stability, battery chemistry, and mechanical performance. This work aims at creating electrospun membranes with improved thermal resistance, structural integrity and moderate ionic conductivity as the next generation LIB separators. Electrospinning process is known as a versatile and straightforward technique to fabricate continuous fibers at nano- and micro- scales. The electrospinning process employs an electrostatic force to control the production of fibers from polymer solutions. Solution and process parameters, including type of polymer and solvent system, concentration of polymer solution, acceleration voltage, and solution feed rate, have been studied to achieve the desirable membrane properties. In this report, the electrospinning parameters affecting morphology and corresponding properties of electrospun membranes, electrospun polymer composite and polymer-metal oxide composite membranes for structural battery applications will be discussed.

With the rapid growth of electric vehicle (EV) market, the mechanical safety of lithium-ion batteries has become a critical concern for car and battery manufacturers as well as the public. Lithium-ion battery cells consist of cathode, anode, separator and shell casing or aluminum plastic cover. Among them, the shell casing provides substantial strength and fracture resistance under mechanical loading, and the failure of the separator determines onset of internal short circuit of the cell. In the first part of this thesis, a plasticity and fracture model of the battery shell casing by taking the anisotropic plasticity and stress-state dependent fracture into account was developed. The shell casing model is calibrated and validated at both specimen and component levels. This shell casing model, together with homogenized jellyroll model could predict mechanical behavior of single cylindrical 18650 cell well and could serve for battery pack crash simulation purposes. Another part of this thesis is mechanical test, characterization and modeling of battery separators since the mechanical properties of separators are crucial to internal shorts of lithium-ion batteries. Mechanical properties of commercially available four typical separators that including polypropylene (PP), trilayer (PP-PE-PP), ceramic-coated and nonwoven separators were compared, such as in-plane tensile strength, out-of-plane compression strength and puncture strength. Two distinct failure modes of dry-processed separators under biaxial loading were observed in the tests and used to explain the differences in short circuit characteristics of same cells. A conservative defection-based failure criterion for predicting of onset of short from experimental data was proposed. Numerical model of separator was developed and it succeeded in predicting the response of PP separator under biaxial loading. Owing to the micro porous semi-crystalline nature of widely used PP separator, interrupted tests of PP separator under different in-plane tension including machine direction, transverse direction and diagonal direction were conducted in order to reveal deformation mechanism at the micrometer level. Through scanning electric microscopy (SEM) observation and X-ray diffraction of deformed regions from interrupted test specimens, deformation sequences of micro fibrils and lamellae blocks of PP separator are reported. Lastly, significant mechanical degradation of separator due to charge-discharge cycling was described.

Abstract:
The battery separator is a component of the conventional battery that for long has been overlooked. Just because it’s the only inactive component, doesn’t mean it’s any less important for the battery cell. Recent trends point to an immense growth of the electrical vehicle-industry, and by so, also the lithium-ion battery separators market. This is because the lithium-ion battery is the most common battery type in commercial electrical vehicles. In one of the major manufacturing processes of the separator, mineral oil is used, to achieve a porous film. This study aims to evaluate different oils interaction with the polymer resin in the manufacturing process. Since most oils used in the battery separator industry today use paraffin rich oils, oils with different naphthenic content is tested to find correlations between the oils properties and the crystallinity or the porosity. No correlations for either the porosity or the crystallinity could be made to the oil’s properties. The images taken with the SEM was not enhanced enough to study the pores themselves or the pore structure of the films. For future studies it is recommended to collect more data to identify outliers so more accurate values are obtained. The methodology needs to be verified to ensure the procedure is reproducible. For the study of the pores and the pore structure, an FE-SEM should be used to achieve greater quality enhancement images on the surface of the films.
Batteri separatorn är en komponent i det konventionella batteriet som länge har förbisetts. Bara för att den är en inaktiv komponent, betyder inte att den är mindre viktig för battericellens prestation. Trender idag pekar mot en enorm tillväxt inom elbils-industrin, och med det även litium-jon batteriseparatorns marknad. Det är för att litium-jon batteriet är det batteriet som vanligen används kommersiellt idag i elbilar. I en av de två stora industriella tillverkningsprocesserna används olja för att åstadkomma en porös film. Denna studie syftar på att utvärdera olika oljors interaktion med polymeren i denna tillverkningsprocess. Eftersom de flesta batteriseparator-industrier idag använder paraffinrik olja så testas oljor med olika mycket naftalensikt innehåll för att hitta korrelationer mellan oljornas egenskaper och kristalliniteten eller porositeten hos filmerna. Inga korrelationer för porositeten eller kristalliniteten kunde göras till oljornas egenskaper. Bilderna tagna med SEM var ej tillräckligt förstorade för att kunna studera vare sig porstorleken eller porstrukturen hos filmerna. För framtida studier rekommenderas att samla in mer data för att kunna utskilja ”outliers” i datan, för att erhålla mer korrekta värden. Metodiken måste även verifieras för att säkerställa att proceduren är reproducerbar. För att studera porerna och porstrukturen, borde en FE-SEM användas för att få mer förstorade bilder med bättre kvalité på filmernas yta.

Abstract:
Due to its extensive application, the safety issue of lithium-ion battery has received increasing attention. For crashworthiness design of battery in electric vehicles, it is of great importance to investigate the response of the battery under mechanical loading and understand the mechanism of internal short circuit. Quasi-static and intermediate strain rate uniaxial tension tests were conducted on the electrodes and the separators. The high speed camera and DIC (digital image correlation) method were adopted to measure the strain while a self-design load cell was used to measure force in dynamic test. Either loading velocity or loading direction was varied in different tests. The upper limit of the test strain rate achieved 66 /sec. All the component materials showed strain rate dependency and separators demonstrated noticeable anisotropy. Quasi-static penetration tests were conducted on two different types of pouch cell using steel and plastic punch heads. For both Type A pouch cell and Type B pouch cell, during penetration process using plastic punch head, no significant voltage drop or temperature rise was observed. During penetration process using steel punch head, only Type A pouch cell produced short circuit. When the punch head was removed, the voltage of the cells could recover to certain level. From post mortem examination, it was found that for a single pouch cell, all the electrodes presented the same fracture mode that the stacked anode and cathode formed several fragments in the penetration path, while the separators in between only formed a central crack when the punch head went through. Since the separators had a larger elongation ratio than the electrodes, the extended separators around the rupture location could block the direct and constant contact between anode and cathode, electrodes and steel punch, which explained why no massive internal short circuit was initiated. The drop tower was used to conduct dynamic penetration test. The results indicated that under dynamic loading, internal short circuit was more likely to be triggered which can be explained by the strain rate effect of the separators. This study highlighted the importance of the separator to the safety performance of pouch cells.
