摘要
Abstract To promote the development of solid‐state batteries, polymer‐, oxide‐, and sulfide‐based solid‐state electrolytes (SSEs) have been extensively investigated. However, the disadvantages of these SSEs, such as high‐temperature sintering of oxides, air instability of sulfides, and narrow electrochemical windows of polymers electrolytes, significantly hinder their practical application. Therefore, developing SSEs that have a high ionic conductivity (>10 −3 S cm −1 ), good air stability, wide electrochemical window, excellent electrode interface stability, low‐cost mass production is required. Herein we report a halide Li + superionic conductor, Li 3 InCl 6 , that can be synthesized in water. Most importantly, the as‐synthesized Li 3 InCl 6 shows a high ionic conductivity of 2.04×10 −3 S cm −1 at 25 °C. Furthermore, the ionic conductivity can be recovered after dissolution in water. Combined with a LiNi 0.8 Co 0.1 Mn 0.1 O 2 cathode, the solid‐state Li battery shows good cycling stability.
