“…Recently, a free‐standing and high‐conductance composite solid electrolyte membrane with a thickness of 120 µm containing a 78Li 2 S‐22P 2 S 5 glass‐ceramic (7822gc) sulfide in PEO or PVDF was fabricated via a liquid‐phase method. [ 138 ] However, increasing polymer content increased the size of the polymer fibers deposited on the surface of sulfide particles from nanowhiskers to microfibers, resulting in a reduction in the ionic conductivity of the electrolyte. To balance ionic conductivity and mechanical strength, an electrolyte composed of 7822gc and 5 wt% PEO was prepared, which exhibited excellent ionic conductivity of 2.07 × 10 −4 S cm −1 at ambient conditions.…”

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.

“…In addition to the inorganic layer, inorganic–organic hybrid interlayer at the lithium/solid electrolyte interface is also adopted to block the interfacial electron transfer and suppress the lithium dendrites formation. [ 188 ] The lithium metal anode protected by succinonitrile‐based plastic crystal electrolyte enables a high capacity retentions for both ASSLBs coupled with LiFePO 4 or polyacrylonitrile‐sulfur (PAN‐S) composites cathodes. [ 189–190 ] Moreover, it has been reported that the pretreatment of Li metal surface by N 2 , [ 191 ] H 3 PO 4 , [ 184 ] and incorporation with a small amount of LiTFSI/Pyr13TFSI ionic liquid [ 192 ] also help to prolong the lifespan of the sulfide‐electrolyte‐based ASSLBs.…”

All‐solid‐state lithium batteries (ASSLBs) are considered as the next generation electrochemical energy storage devices because of their high safety and energy density, simple packaging, and wide operable temperature range. The critical component in ASSLBs is the solid‐state electrolyte. Among all solid‐state electrolytes, the sulfide electrolytes have the highest ionic conductivity and favorable interface compatibility with sulfur‐based cathodes. The ionic conductivity of sulfide electrolytes is comparable with or even higher than that of the commercial organic liquid electrolytes. However, several critical challenges for sulfide electrolytes still remain to be solved, including their narrow electrochemical stability window, the unstable interface between the electrolyte and the electrodes, as well as lithium dendrite formation in the electrolytes. Herein, the emerging sulfide electrolytes and preparation methods are reviewed. In particular, the required properties of the sulfide electrolytes, such as the electrochemical stabilities of the electrolytes and the compatible electrode/electrolyte interfaces are highlighted. The opportunities for sulfide‐based ASSLBs are also discussed.

“…The combination of sulfides with a polymer not only show improved ionic conductivity but also have an extended electrochemical stability window of 5.7 V (Zhao et al, 2016b). A study utilizing high loadings (95 wt%) of a 78Li 2 S-22P 2 S 5 glass type ceramic compared the performance of HSEs with PVDF and PEO polymer matrices (Zhang et al, 2020). While PVDF provided a higher ionic conductivity (4.54 × 10 −4 S/cm) than PEO (1.27 × 10 −4 S/cm) at room temperature, the LiTFSI salt was found to be inhomogeneously distributed in the PVDF composite.…”

Lithium-ion batteries (LIBs) have attracted worldwide research interest due to their high energy density and long cycle life. Solid-state LIBs improve the safety of conventional liquid-based LIBs by replacing the flammable organic electrolytes with a solid electrolyte. Among the various types of solid electrolytes, hybrid solid electrolytes (HSEs) demonstrate great promise to achieve high ionic conductivity, reduced interfacial resistance between the electrolyte and electrodes, mechanical robustness, and excellent processability due to the combined advantages of both polymer and inorganic electrolyte. This article summarizes recent developments in HSEs for LIBs. Approaches for the preparation of hybrid electrolytes and current understanding of iontransport mechanisms are discussed. The main challenges including unsatisfactory ionic conductivity and perspectives of HSEs for LIBs are highlighted for future development. The present review provides insights into HSE development to allow a more efficient and target-oriented future endeavor on achieving high-performance solid-state LIBs.
