Recent advances of covalent organic frameworks in lithium ion batteries

Abstract

Covalent organic frameworks (COFs) are emerging porous polymer materials. They are characterized by functionalization of their surface chemical properties, and excellent physical and chemical stability. This review focuses on the advances of COFs in lithium ion batteries (LIBs) regarding the active sites and discusses the redox mechanisms of active sites. Furthermore, the modification methods of COFs as electrode materials are analyzed and summarized.
