2D Nitrogen-Rich π-Conjugated Microporous Polymer for High Performance of Lithium-Ion Batteries

Abstract

Novel 2D graphene analogues with high conductivity is highly demanded as anode materials for lithium-ion batteries (LIBs). Here we report the preparation and characterization of the π-conjugated microporous polymer NGA-CMP with experimental bandgap of 2.34 eV. Heated sample NGA-CMP400 is used for the first time as anode materials for LIBs. The NGA-CMP400 achieves high reversible capacity of 701 mAh g-1 at 1 A g-1 with extremely stable cycling performance over 500 cycles. The rational design of this kind of graphene-like 2D material with inherent porosity and enhanced electronic conductivity possesses important significance in carbon-based anode materials for LIBs.
