摘　　要：The emergence of solid-state batteries(SSBs)has generated significant interest in the field of energy storage,primarily due to their advantages such as high safety,high energy density and long lifetime.Solid state electrolytes(SSEs)play a crucial role in SSBs,which not only affects the ion transport efficiency,but also relates to the overall performance and stability of the batteries.In recent years,SSEs based on covalent organic frameworks(COFs)have become a research focus in the battery field because of their unique structural characteristics and excellent performance.This review aims to provide an overview of the application and latest progress of COF-based SSEs in the field of advanced batteries.Firstly,the structural features of COFs and their advantages as SSEs are briefly introduced,followed by a summary of the types of COF-based SSEs(including neutral COF-based SSEs and ionic COF-based SSEs).The latest research progress in lithium ion batteries(LIBs),lithium metal batteries(LMBs),proton exchange membrane fuel cells(PEMFCs)and other advanced batteries recently is also discussed.Finally,we summarize and outlook the current research status,the challenges faced in practical application,the future research directions and application prospects of COF-based SSEs.
