“…Due to the low ionic conductivity of PEO at room temperature, it is necessary to discover other novel hosts for solid polymer electrolytes. In addition to PEO, various polymer hosts have been applied in solid polymer electrolytes such as poly(acrylonitrile) (PAN), [ 185–188 ] poly(methyl methacrylate) (PMMA), [ 189–192 ] poly(vinylidene fluoride) (PVDF), [ 193–198 ] and poly(vinylidene fluoride‐co‐hexafluoropropylene) (PVDF‐HFP).

“…It acts as a promising polymer matrix in solid polymer electrolytes with high thermal stability, mechanical stability, and electrochemical stability. Sim et al [ 185 ] prepared a PAN‐based polymer electrolyte by dissolving 60 wt% PAN and 40 wt% LiTFSI in N , N ‐dimethylformamide (DMF). This material delivered a high ionic conductivity of 2.54 × 10 −4 S cm −1 at 80 °C.…”

Lithium–sulfur (Li–S) batteries are one of the most promising next‐generation energy storage systems due to their ultrahigh theoretical specific capacity. However, their practical applications are seriously hindered by some inevitable disadvantages such as the insulative nature of sulfur and Li2S, volume expansion of the cathode, the shuttle effect of polysulfides, and the growth of lithium dendrites on the anode. Of these, the polysulfide shuttle effect is one of the most critical issues causing the irreversible loss of active materials and rapid capacity degradation of batteries. Herein, modified separators with functional coatings inhibiting the migration of polysulfides are enumerated based on three effects toward polysulfides: the adsorption effect, separation effect, and catalytic effect. To solve the shuttle effect problem, researchers have replaced liquid electrolytes with solid‐state electrolytes. In this review, solid‐state electrolytes for lithium–sulfur batteries are grouped into three categories: inorganic solid electrolytes, solid polymer electrolytes, and composite solid electrolytes. Challenges and perspectives regarding the development of an optimized strategy to inhibit the polysulfide shuttle for enhancing cycle stability in lithium–sulfur batteries are also proposed.

“…The common method to obtain a uniform polymer solution is to dissolve PAN into an organic solvent with high boiling point such as N , N ‐dimethylformamide (DMF) and dimethylsulfoxide (DMSO) that consume much energy to remove, which may be problematic for the large‐scale production of PAN‐based PSEs. [ 34,35 ] In addition, the interface between PAN and the Li metal anode is not stable, which needs to be addressed.…”

Polymer‐based solid electrolytes (PSEs) have attracted tremendous interests for the next‐generation lithium batteries in terms of high safety and energy density along with good flexibility. Remarkable performances have been demonstrated in PSEs, which endowed PSEs with the potential to replace liquid electrolytes to meet the market demands. In this review, polymer matrices, different polymer architectures, and functional filler materials used in PSEs are discussed to explore the design concepts, methodologies, working mechanisms, and pros and cons of various PSEs. In addition, their recent notable applications in all‐solid‐state lithium ion batteries, lithium–sulfur batteries, suppression of lithium dendrites, and flexible lithium batteries are also introduced. Finally, the challenges and future prospects are sketched to provide strategies to explore novel PSEs for high‐performance all‐solid‐state lithium batteries.

Przewodniki szybkich jonów, zwane również superprzewodnikami jonowymi oraz elektrolitami stałymi, są ciałami stałymi o przewodnictwie jonowym porównywalnym do tego występującego w elektrolitach ciekłych. Niektóre rodzaje jonów, takie jak: Ag + , Cu + , Li + , F -, O 2czy H + , w ciele stałym mogą poruszać się niemal tak szybko jak w cieczy. Właściwość ta, choć zaobserwowana jedynie w ograniczonej liczbie materiałów jest kluczowym czynnikiem umożliwiającym zastosowanie w wielu nowoczesnych urządzeniach jak na przykład baterie, ogniwa paliwowe czy urządzenia elektrochromowe. Niniejszy przegląd zawiera opis materiałów wykorzystujących jony litu Li + jako źródło transportu ładunku. Przedstawione zostały rodzaje elektrolitów, technologie osadzania elektrolitów stałych oraz odmiany strukturalne i najważniejsze właściwości elektryczne elektrolitów stałych mogących znaleźć zastosowanie w urządzeniach elektrochromowych.
