Abstract
En 中文
Halide solid electrolytes have become key candidate materials for all-solid-state lithium batteries (ASSLBs) due to their high ionic conductivity; wide electrochemical window; and good compatibility with high-voltage cathodes. This paper reviews their material chemistry; crystal structure; synthesis; and characterization methods; with a focus on analyzing the composition–structure–performance relationship; and explores the effects of halogen types and their mixtures on ion transport and stability. Meanwhile; it analyzes the challenges at the cathode/anode interface and summarizes strategies such as element doping; interface engineering; and mechanical performance and moisture resistance optimization. Despite significant progress in the laboratory; practical applications are still constrained by issues such as high cost; moisture sensitivity; and unstable interfaces with lithium metal. In the future; efforts should be focused on low-cost alternatives; improved moisture resistance; and multi-functional interface design; combined with high-throughput computing and advanced characterization; to accelerate the industrialization process in high-energy-density ASSLBs.
