采用室温冷压法制备了Li6.3La3Zr1.65W0.35O12（LLZO）-Li 6PS 5Cl（LPSC）复合电解质及含LLZO-LPSC的全固态电池。改变LPSC：LLZO的比例，并研究了相应复合电解质的微观结构、离子电导率和电化学性能;复合电解质的离子电导率比LLZO高三到四个数量级。复合电解质的高电导率归因于具有高锂离子电导率（~10−4 S·cm−1）的软LPSC颗粒的增强的相对密度和混合规则。由LiNi0.8Co0.1Mn0.1O2（NCM 811）阴极和LLZO：LPSC = 7：3和6：4的复合电解质组成的全固态电池（ASSC）在0.1 C和室温下的比容量分别为163和167 mAh·g−1。此外，与复合电解质的ASSC的充电-放电曲线显示，NCM 811阴极和LLZO-LPSC复合电解质之间成功地形成了良好的界面接触。
Li6.3La3Zr1.65W0.35O12 (LLZO)-Li6PS5Cl (LPSC) composite electrolytes and all-solid-state cells containing LLZO-LPSC were fabricated by cold pressing at room temperature. The LPSC:LLZO ratio was varied, and the microstructure, ionic conductivity, and electrochemical performance of the corresponding composite electrolytes were investigated; the ionic conductivity of the composite electrolytes was three or four orders of magnitude higher than that of LLZO. The high conductivity of the composite electrolytes was attributed to the enhanced relative density and the rule of mixture for soft LPSC particles with high lithium-ion conductivity (~10−4 S·cm−1). The specific capacities of all-solid-state cells (ASSCs) consisting of a LiNi0.8Co0.1Mn0.1O2 (NCM811) cathode and the composite electrolytes of LLZO:LPSC = 7:3 and 6:4 were 163 and 167 mAh·g−1, respectively, at 0.1 C and room temperature. Moreover, the charge–discharge curves of the ASSCs with the composite electrolytes revealed that a good interfacial contact was successfully formed between the NCM811 cathode and the LLZO-LPSC composite electrolyte.
