摘要

Covalent organic frameworks (COFs) are an emerging porous polymer material that has been extensively studied and used to develop advanced membranes for rechargeable batteries. Demand-oriented design at the molecular/atomic level to get the optimal separator may be possible thanks to the customizable structure of COFs. For example, their unique porous structure facilitates electrolyte penetration and ion transport, making them ideal for battery separators. More active centers for electrochemical reactions can be added by changing the chemical makeup of COFs. As a result, in the field of LIBs, COFs and their associated composites have been thoroughly and extensively researched. We mainly focus on the synthetic design of COF materials, synthetic methods, and the application of COF materials in lithium separator, modification method design, application prospects in lithium separator, challenges, and improvement strategies which were prospected.
