A covalent organic framework based on multi-carbonyl as anode material for lithium-organic batteries

Abstract

A covalent organic framework (COF) with multi-carbonyl was synthesized by a condensation reaction between 1,3,5-triformyl chlorobutanediol (TFP) and 2.5-diamino benzene sulfonic acid (PaSO3H), It is using as anode materials for lithium-ion batteries (LIBs). Benefiting from the rigid porous network structure of COFs (TFP-PaSO3H) and the synergistic effect of covalent bonds, it shows good electrochemical performance, including a high reversible capacity of 427.7 mAh g−1 at 200 mA g−1 after 300 cycles. This contribution shows a broad application prospect of COF anode in lithium-organic batteries.
