  Abstract

Developing high-performance solid-state electrolytes is being researched extensively because they are a viable alternative to the inflammable liquid-phase organic electrolytes used in lithium ion batteries (LIBs). In this study, the performance of solid-state LIBs using a Li7La3Zr2O12 (LLZO)/poly(ethylene oxide) (PEO) composite electrolyte in conjunction with SnO₂-based electrodes was systematically optimized. The LIB charge/discharge performances were initially evaluated as a function of LLZO:PEO mass ratios (e.g., 20:80, 40:60, 60:40, 80:20). The best performing 20:80 LLZO:PEO composite electrolyte was then integrated with high-surface-area SnO₂ nanowire electrodes to further enhance the fast-charging capabilities of solid-state LIBs.
