Lithium Phosphorus Sulfur Chlorine Sulfide (LPSC) Composite Solid Electrolyte
All-solid-state batteries have the characteristics of high energy density, long cycle lifeand high safety, which is the development direction of the next generation of electrochemical energy storage. Solid-state electrolytes are the core components of all-solid-state batteries, and sulfide electrolytes have attracted extensive attention due to their advantages of high ionic conductivity and good mechanical ductility. As one of the most studied sulfide electrolytes in recent years, lithium-phosphorus-sulfur-chloride sulfide (LPSC) has high ionic conductivity and relatively low cost, but its practical application is limited by shortcomings such as poor stability and poor compatibility of positive and negative electrode materials. The composite solid-state electrolyte has good electrochemical and mechanical properties, and the composite solid-state electrolyte is prepared by modifying the LPSC with polymers, aiming to improve the interfacial compatibility and electrochemical stability of the LPSC. In this paper, the basic composition, recombination mode, modification strategy and ion transport mechanism of LPSC composite solid electrolyte are reviewed, and the future research direction and application prospect of LPSC composite electrolyte are prospected.
