ABSTRACT: Organic electrode materials play a crucial role in environmentally friendly
and sustainable lithium-ion batteries (LIBs) due to their abundance, high theoretical
capacity, inexpensiveness, and recyclability. However, critical issues such as fewer redox
active sites and poor structural stability limit their extensive application in LIBs. Herein,
a unique covalent organic framework (Tp-Azo-COF) with a dual active site of NN and
CO is designed and successfully applied as the anode material for LIBs. Benefifiting
from its abundance of active sites, large conjugate structure, large surface area, and
accessible Li+transport channels, the Tp-Azo-COF anode materials present high
electrochemical kinetics and structural stability. The assembled LIBs deliver a specifific
capability of 305.97 mAh g?1at a current density of 1000 mA g?1after 3000 cycles. This
work may inspire avenues for the development of advanced organic materials of
inexpensive, sustainable, and durable rechargeable batteries.
