“…Since the first study on poly(ethylene oxide) (PEO) -based electrolyte for Li-S cells in the late of 1980s by DeGott, 37 several types of solid electrolytes have been investigated as Li-ion conducting materials for ASSLSBs, including those based on pure polymeric components, [38][39][40][41][42][43][44][45][46][47][48][49] ceramic electrolytes, [50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66][67] and composite electrolytes (mix of ceramic and other electrolytes). [68][69][70] Generally, PEs can be classified into two categories: solid polymer electrolytes (SPEs) and gel polymer electrolytes (GPEs).…”

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...

“…Solid PEs based on PEO, [3,10,[120][121][122][123][124][125] and gel PEs based on PEO [11], PVdF/P(VdF-HFP) [12,34,46,120,126], polyacrylonitrile (PAN) [127], poly (methylmethacrylate) (PMMA) [128], and acrylates/ methacrylates [129] have been studied for Li/S cells.

Lithium batteries based on elemental sulfur as the cathode-active material capture great attraction due to the high theoretical capacity, easy availability, low cost and non-toxicity of sulfur. Although lithium/sulfur (Li/S) primary cells were known much earlier, the interest in developing Li/S secondary batteries that can deliver high energy and high power was actively pursued since early 1990's. A lot of technical challenges including the low conductivity of sulfur, dissolution of sulfurreduction products in the electrolyte leading to their migration away from the cathode, and deposition of solid reaction products on cathode matrix had to be tackled to realize a high and stable performance from rechargeable Li/S cells. This article presents briefly an overview of the studies pertaining to the different aspects of Li/S batteries including those that deal with the sulfur electrode, electrolytes, lithium anode and configuration of the batteries.

“…The added-ZrO 2 filler in a PEO-LiCF 3 SO 3 filler significantly promoted the ionic conductivity of the composite polymeric membrane. Efforts have also been made to replace the highly reactive anode material with alloy anodes with same type of nanocomposite polymer electrolytes (Jeng et al, 2007). Jeddi et al (2013a,b) proposed a novel polymer electrolyte by blending poly(vinylidene fluoride-co-hexafluoropropene) (PVdF-HFP) with monofunctional poly(methyl methacrylate) (PMMA) containing inorganic trimethoxysilone domains.…”

This review article mainly encompasses on the state-of-the-art electrolytes for lithiumsulfur batteries. Different strategies have been employed to address the issues of lithiumsulfur batteries across the world. One among them is identification of electrolytes and optimization of their properties for the applications in lithium-sulfur batteries. The electrolytes for lithium-sulfur batteries are broadly classified as (i) non-aqueous liquid electrolytes, (ii) ionic liquids, (iii) solid polymer, and (iv) glass-ceramic electrolytes. This article presents the properties, advantages, and limitations of each type of electrolytes. Also, the importance of electrolyte additives on the electrochemical performance of Li-S cells is discussed.
