Covalent Organic Frameworks as Emerging Battery Materials

Batteries & Supercaps, Journal Year: 2023, Volume and Issue: 6(4)

Published: Jan. 23, 2023

Abstract Covalent organic frameworks (COFs) are emerging as promising energy storage materials due to their unique characteristics, such adjustable thickness, designable topology, superior stability and controllable pore size distribution. Consequently, COFs can provide diversified high‐rate carrier transport pathways, the performance of be easily improved by adjusting conjugated skeleton types, overlapping p‐electron clouds between stacks, modifying open channels with functional groups. The state‐of‐the‐art electrode based on synthetic method electrochemical in recent years summarized discussed this review. synthesis method, topological structure application metal ion (such Li + , Na K Zn 2+ Mg Al 3+ et. al) batteries electrodes critically accounted. Finally, we briefly discuss major challenges field that needs addressed pave way for industrial applications. Although there still many arduous tasks tackled, burgeoning COFs‐related technologies applications a ponderable commercial process short run.
