| description | In recent years, solid-state lithium-ion batteries with high safety and excellent performance have become a research hotspot. Garnet Li7La3Zr2O12 (LLZO) has been widely used in lithium-ion batteries because of its high ionic conductivity, wide electrochemical window, excellent thermal performance, and promising stability. In this study, Ga-LLZO was prepared by the electrospinning method and combined with PVDF-HFP to prepare a composite polymer electrolyte. The addition of 15 wt% Ga-LLZO nanofibers in the electrolyte improved the ionic conductivity, reaching 8.92 × 10−4 S·cm−1 at room temperature. The electrochemical window for PVDF-HFP/LiTFSI/Ga-LLZO composite polymer electrolyte was 5.2 V vs Li/Li+. In addition, LiFePO4|PVDF-HFP/LiTFSI/Ga-LLZO|Li exhibited good cycling performance and rate capability. High-performance composite electrolyte films of ceramic nanofiber Ga-LLZO and polymer were successfully prepared for high-performance solid-state lithium batteries.
