摘要
En 中文
Solid-state electrolyte and solid-state air electrode design are the main bottlenecks inhibiting the development of solid-state Li-O-2 batteries (SSLOBs). Herein, we report an ionically superconductive halide electrolyte which regulates the air electrode interface and enhances the performance of SSLOBs. As this is the first investigation of this halide electrolyte in a Li-O-2 battery, a comprehensive study of the stability of this electrolyte is conducted. The high ionic conductivity of Li3InCl6 (up to 1.3 x 10(-3) S cm(-1)) and its solution-based preparation method enable it to work like a liquid electrolyte modifier at the air electrode, uniformly regulating the function of the interface. As a result, Li-O-2 batteries with Li3InCl6 exhibit decreased interfacial resistance and enhanced decomposition of discharge products. The present study may open a new window of opportunity toward the development of SSLOBs.
