Structure-modulated crystalline covalent organic frameworks as high-rate cathodes for Li-ion batteries

Author affiliations

Abstract

Sustainable and resourceful organic materials are of long-standing interest for lithium-ion batteries. However, the lack of structural stability and cyclic capability is still the bottleneck for their practical use. Here, two new chemically stable naphthalimide-based crystalline covalent organic frameworks (COFs) were first synthesized through a simple solvothermal route. Excellent electrochemical performances were achieved as cathode materials for Li-ion batteries, mainly due to their open ordered nanoporous framework and robust structure. Moreover, their electrochemical performance can be improved by simply altering the linker of COFs at the molecular level. This work provides a possible approach to obtain the desired performance by structural modulation of organic materials.
