Abstract:

Owing to their favorable oxidative stability, high ionic conductivity, and good mechanical processability, halide solid-state electrolytes have emerged as promising electrolyte candidates for all-solid-state batteries. With the development of systems such as chlorides, oxychlorides, and nitride-chlorides, halide solid-state electrolytes have made significant progress in ionic transport performance and structural regulation. However, these materials are still mainly at the stage of laboratory-scale preparation and cell validation, and their scalable application still faces several issues. This review summarizes the major preparation methods, including ball milling, solid-state reaction, solution-based synthesis, vapor-phase deposition, and related hybrid processing strategies. The characteristics of different processes in terms of structural regulation and scalable preparation potential are compared, and the key issues that need to be addressed during the transition from laboratory preparation to scalable manufacturing are further analyzed, including batch-to-batch consistency control, manufacturing-cost reduction, environmental- stability improvement, process controllability, and compatibility with practical battery-manufacturing workflows, thereby providing a reference for process optimization, scalable preparation, and application research of halide solid-state electrolytes in all-solid-state batteries.

Key words: Halide solid-state electrolyte, All-solid-state battery, Preparation strategy, Scalable preparation
