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 Li 3 Zr 2 Si 2 [Formula: see text] (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 × 10[Formula: see text] S ⋅ cm[Formula: see text] at 25 ∘ 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.
