摘要

This study develops a new electrode material by hybridizing covalent organic frameworks (COFs) with carbon nanotubes to enhance charge transfer

stability

and cycling performance in lithium-ion batteries.

Abstract

This study focuses on the development and optimization of electrode materials composed of covalent organic frameworks (COFs) integrated with carbon nanotubes (CNTs) for lithium-ion battery applications. The findings reveal that incorporating CNTs into COFs markedly enhances their electrochemical performance by reducing charge transfer resistance and accelerating charge transport kinetics. Impressively

the COFs/CNT composites delivered a high specific capacity of 307 mAh·g

–1

at a low current density of 0.05 A·g

–1

and maintained strong capacity retention even at elevated current densities. Furthermore

the composites demonstrated outstanding cycling stability and structural robustness

retaining significant capacity after 1000 charge/discharge cycles.
