Abstract

Herein, we report the preparation of porous polyimide (PI) with a cost-effective synthesis process by polycondensation between melamine and dianhydride monomers. The prepared porous PI served as a cathode for lithium-ion batteries (LIBs), and delivers a high discharge platform of 2.1 V and satisfactory electrochemical performance. Thus, the porous PI cathode provides another choice for LIBs.
