“…Thus, its practical applications were limited. Clearly, it is extremely urgent to seek some electrolytes with superior safety for the rapid development of Li-ion and/or Li batteries in the next-generation large-scale applications [5,6]. All-solid-state Li-ion batteries are considered to be most promising to address the safety challenges of the current Li-ion batteries, which possess great advantages over the liquid or gel electrolytes, including better safety, non-flammability, non-leakage and excellent design flexibility [7,8].…”

Ionic liquid has relatively high conductivity at room temperature and good electrochemical stability. Ionic liquid polymer electrolytes have some advantages of both ionic liquid and polymer. In this work, 1-alkyl-3-(2′,3′-dihydroxypropyl)imidazolium chloride (IL-Cl) was incorporated into waterborne polyurethane chain to composite all-solid-state polymer electrolyte matrices. The structure, thermal stability, mechanical property and ionic conductivity of the matrices were investigated by Fourier transform infrared spectroscopy (FTIR), thermogravimetric Analysis (TGA), tensile measurement and electrochemical impedance spectroscopy (EIS). The results demonstrated that when the content of IL-Cl was 14 wt%, the mechanical property of film was optimized, with a maximum tensile strength of 36 MPa and elongation at break of 1030%. In addition, as for the film with IL-Cl content of 16 wt%, its oxygen index value increased to 25.2% and ionic conductivity reached a maximum of 1.2 × 10−5 S·cm−1 at room temperature, showing high flame retardancy and ionic conductivity.

“…DSC analysis evidences the correlation of change in T g with respect to salt concentration. Also, the aromatic nature of Huckel-type anions provides flexibility to PEO matrix which supports faster ion transport as evidenced by an enhancement in ionic conductivity.Ma et al[44] reported the preparation of SPE based on perfluorinated sulfonimide salt-based SPEs, composed of lithium (trifluoromethanesulfonyl) (n-nonafluorobutanesulfonyl)imide (Li[(CF 3 SO 2 )(n-C 4 F 9 SO 2 )-N], LiTNFSI) and poly (ethylene oxide) (PEO) using solution cast technique.

In this review, latest updates in the poly (ethylene oxide) based electrolytes are summarized. The ultimate goal of researchers globally is towards the development of free standing solid polymeric separator for energy storage devices. This single free standing solid polymeric separator may replace the liquid and separator (organic/Inorganic) used in existing efficient/smart energy technology. As an example polyethylene oxide (PEO) consist of an electron donor rich group which provides coordinating sites to the cation for migration. Owing to this exclusive structure PEO exhibits some remarkable properties such as; low glass transition temperature, excellent flexibility and ability to make complexation with various metal salts which are unattainable by another polymer host. Hence, the PEO is the most emerging candidate that have been examined or is currently under audition for application in energy storage devices. So, this review article first provides the detailed study of the PEO properties, characteristic of constituents of polymer electrolyte and suitable approaches for the modification of polymer electrolytes. Then, the synthesization and characterizations techniques are outlined. The structures, characteristics, and performance during charge-discharge of four types of electrolyte/separators which are Liquid, Plasticized, and dispersed/intercalated electrolyte are highlighted. The suitable ion transport mechanism proposed by researchers in different renowned group have been discussed for better understanding of the ion dynamics in such systems.Keywords: polyethylene oxide, constituents of polymer electrolytes, structural and microstructural properties, electrochemical properties summarizes the requirements for selection of electrolyte cum separator for efficient lithium-ion battery system [4].At, present, LIB is the ideal choice for the automotive sector by Companies including Tesla Inc. and Volkswagen AG due to ease of transportation, environmentally friendly, less cost [5]. Allied Market Research published a report entitled, "World Lithium-Ion Battery Market: Opportunities and Forecasts, 2015-2022" and the main point was that the global LIB market is expected to generate revenue of $46.21 billion by 2022, with a CAGR of 10.8% during the forecast period (2016)(2017)(2018)(2019)(2020)(2021)(2022). At a 37 percent revenue share, Li-ion is the battery of choice for portable devices and the electric vehicles. There are no other systems till now that threaten the market of LIB today [figure 2].Recently in 2017, John Goodenough, inventor of Li-ion battery has developed the first all-solid-state battery cells using sodium-or lithium-coated glass electrolyte and claimed that new battery cells have three times more energy density (1,200 charge-discharge cycles) in comparison to existing rechargeable batteries. He concluded that they store and transmit energy at temperatures (-20 o C to 60 o C) lower than traditional lithium-ion packs and can be made using globally abundant supplies of sodium. One advantage of this...

All-solid-state lithium-sulfur batteries (ASSLSBs) offer a means to enhance the energy density and safety of the state-of-art lithiumion batteries (LIBs), due to their high gravimetric energy density, low cost and environmental benignancy. In this work, the status of the research advances and perspectives on several types of solid electrolytes (SEs) developed for ASSLSBs are reviewed. The promises and challenges of utilizing SEs are discussed taking into account both theoretical calculation and experimental results, in hope of shedding some lights on future design of high energy density, cost competitive, and safe Li-S batteries. Lithium-sulfur (Li-S) batteries have been extensively investigated for lightweight applications (e.g., aircraft, artificial satellite, and unmanned aerial vehicles), and large-scale stationary energy storage, owing to their high gravimetric energy density, low cost, and environmental friendliness.1-3 The deployment of Li-S batteries into commercial market is hampered by several seemingly intrinsic problems resulting from the complex cell chemistry. Firstly, the electronically insulating nature of elemental sulfur (S 8 ) and end-product lithium sulfide (Li 2 S) leads to unstable electrochemical contact within S cathode. [4][5][6][7] Secondly, the soluble intermediates of polysulfide (PS) can diffuse between the cathode and anode (i.e., shuttle effect of PS), generating an active material loss in S cathode and degrading metallic Li anode. [4][5][6][7][8][9] Thirdly, the formation of 'dead' Li and Li dendrites upon cycling could not only decrease the Coulombic efficiency but also raise safety issues. [10][11][12] In recent years, various strategies have been attempted to overcome the above-mentioned problems. Most of the efforts have been devoted to enhance the electrochemical performance of Li-S batteries using well-designed cathode materials. 13 The diffusion of polysulfide species generated during discharge into electrolytes can be significantly suppressed by infusing sulfur into carbon materials in the cathode with an adequately controlled and engineered porosity and pore size, thus increasing the practical capacity and cyclability of Li-S batteries. These rational and creative strategies of cathode design have been covered by a number of recent reviews. 7,14,15 Besides, new binders (e.g., poly(ethylene oxide) (PEO) 16 and carboxymethycellulose (CMC) 17,18 ) have been employed for guarantying the integrity of the morphology and structure of S cathode, and enhancing the adhesion to current collector. The modification of separators (e.g., multiwall carbon nanotubes coated polypropylene 19 and lithiated Nafion 20 ) have been also developed for reducing the migration of polysulfides, thus mitigating the shuttle effect of PS. 21Apart from the strategies mentioned above, another approach, focusing on electrolyte formulation and modification, has been proved to be effective. The performances of Li-S batteries are largely affected by the electrolyte recipes, such as the type and identity of so...
