“…The novel PCPI − and Huckel-type anions showed ionic conductivities on the order of 0.1 mS cm −1 above 50 and is higher than PEO 16 NaPF 6 based system. At 70 °C, PEO 16 NaTCP showed ionic conductivity values (so-called liquid-like) greater Judez et al [45] reported the preparation of polymer electrolyte based on lithium bis(fluorosulfonyl)imide Thiam et al [47] prepared the solvent-free and oligomer-free 3D polymer electrolytes. The DSC analysis shows the decrease of T m and ∆H m after cross-linking and it may be due to the constraint produced by the cross-linking which reduces the tendency of the chain re-organization.…”

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...

“…On the other hand, the stability and compatibility with the metal lithium anode interface is among the most urgent challenges to be addressed in order to ensure long‐term stability . For example, in the ASSLSBs using the widely used PEO‐lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) SPE, the solid electrolyte interphase (SEI) layer formed on the lithium anode suffers from inferior quality, which directly lead to lithium polysulfide shuttling even in the earliest charge/discharge cycling . Therefore, it is important to stabilize the lithium anode interface and keep lithium polysulfides from shuttling in the SPE.…”

Solid polymer electrolytes (SPEs)-based all-solid-state lithium-sulfur batteries (ASSLSBs) have attracted extensive research attention due to their high energy density and safe operation, which provide potential solutions to the increasing need for harnessing higher energy densities. There is little progress made, however, in the development of ASSLSBs to improve simultaneously energy density and long-term cycling life, mostly due to the "shuttle effect" of lithium polysulfide intermediates in the SPEs and the low interfacial compatibility between the metal lithium anode and the SPE. In this work, the issues of solid/solid interfacial architecturing through atomic layer deposition of Al 2 O 3 on poly(ethylene oxide)-lithium bis(trifluoromethanesulfonyl)imide SPE surface are effectively addressed. The Al 2 O 3 coating promotes the suppression of lithium dendrite formation for over 500 h. ASSLSBs fabricated with two layers of Al 2 O 3 -coated SPE deliver high gravimetric/areal capacity and Coulombic efficiency, as well as excellent cycling stability and extremely low self-discharge rate. This work provides not only a simple and effective approach to boost the electrochemical performances of SPE-based ASSLSBs, but also enriches the fundamental understanding regarding the underlying mechanism responsible for their performance.

“…The developed polymer-based SSEs demonstrated high ionic conductivity and good accommodation with Li metal anode which breaks the bottleneck that allow the polymer-based ASS Li-S batteries operating at ambient temperature. Many groups have attempted to develop hybrid electrolytes with the combination of polymer and oxide-based electrolytes, which demonstrated enhanced stability and conductivity [411][412][413][414][415]. Despite the excellent electrochemical performance, the loading of these sulfur and Li 2 S-based cathodes are unsatisfactory and unsuitable for commercial application.…”

Lithium-sulfur (Li-S) batteries have been considered as one of the most promising energy storage devices that have the potential to deliver energy densities that supersede that of state-of-the-art lithium ion batteries. Due to their high theoretical energy density and cost-effectiveness, Li-S batteries have received great attention and have made great progress in the last few years. However, the insurmountable gap between fundamental research and practical application is still a major stumbling block that has hindered the commercialization of Li-S batteries. This review provides insight from an engineering point of view to discuss the reasonable structural design and parameters for the application of Li-S batteries. Firstly, a systematic analysis of various parameters (sulfur loading, electrolyte/sulfur (E/S) ratio, discharge capacity, discharge voltage, Li excess percentage, sulfur content, etc.) that influence the gravimetric energy density, volumetric energy density and cost is investigated. Through comparing and analyzing the statistical information collected from recent Li-S publications to find the shortcomings of Li-S technology, we supply potential strategies aimed at addressing the major issues that are still needed to be overcome. Finally, potential future directions and prospects in the engineering of Li-S batteries are discussed.
