摘要：

Owing to their high ionic conductivity and excellent flexibility, composite polymer electrolytes (CPEs) have been widely studied in solid lithium metal batteries (SLMBs). In this study, a new solid electrolyte of NASICON-type Li3Zr2Si2PO12 (LZSP) was prepared by the sol-gel method, and then a new type of CPE membrane containing LZSP and Poly(vinylidene fluoride) (PVDF) was synthesized by slurry-casting method. The CPE membrane presented much higher ionic conductivity of 5.66 x 10(-5) S . cm(-1) at 25(circle)C and stronger electrochemical stability compared to the one without LZSP. In addition, the cells containing the composite electrolyte membrane exhibited considerable rate performance and cycle performance.
