Constructing an Adaptive Flexible Interphase on Halide Electrolytes by Lewis‐Acid‐Induced Polymerization for High‐Voltage All‐Solid‐State Lithium Batteries
All‐solid‐state lithium batteries (ASSLBs) combining halide solid electrolytes (HSEs) with high‐nickel layered oxide cathodes offer great promise for high energy density, yet they suffer from severe interfacial issues such as oxidative decomposition, mechanical degradation, and chemical incompatibility with sulfide...
