Abstract: Polyimide (PI) is a polymer synthesized by thermal imination of dianhydride and diamine as raw materials. As a battery electrodes material, it boasts high theoretical capacity, high mechanical strength and easy recovery. However, its insulation limits the utilization rate of internal active sites, resulting in poor rate performance of the battery. A research review is conducted concerning the improvement of the structural stability through enlarging conjugate structure and the introduction of more carbonyl structure (C=O) to increase PI redox center site. In order to obtain higher battery capacity, PI, carbide and graphene combination, the hybridization of carbon nanotubes and the electrostatic spinning process are applied to improve electrochemical performance of battery electrode. The research of other materials based on PI is summarized as well. And the current research direction of PI is prospected.
