Abstract
Abstract Nowadays solid‐state batteries have become a hot spot in the research of batteries and a significant candidate for commercial batteries for the increasing demands for good safety and excellent energy density. Metal‐organic frameworks (MOFs) have been considered as suitable materials for solid‐state electrolytes (SSEs) for the merits of regular channels and large specific surface areas, which can provide a promising structural platform for fast‐ion conduction. Therefore, numerous kinds of MOF‐based SSEs with enhanced electrochemical performance have been successfully synthesized and studied in recent years. In this review, the recent progress (synthesis methods, physical and chemical characteristics) of MOF‐based SSEs for secondary batteries have been summarized. Finally, the challenges and opportunities faced by the future development in this field are put forward, hoping to provide some enlightenment for the synthesis of MOF‐based SSEs, so as to create more efficient, long‐lasting, and safe SSE‐based secondary batteries.
