Perylene-dianhydrides (PTCDA) derived polyimides based organic cathode electrodes for high-power and long-cycle secondary lithium-ion batteries (LIBs) have gained attention owing to their good cycling stability and good rate capabilities. Here, we report a study on electron-rich pyrene group substituted at the 1,7-bay position of PTCDA polyimides as novel cathode organic materials for a secondary LIBs application. The synthesized perylene polyimides were characterized using various conventional techniques such as Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and cyclic voltammetry (CV) analyses. We demonstrated organic LIBs using these perylene polyimides as the cathode material and resulted in excellent electrochemical properties with high reversible capacity along with good rate of capability in the voltage range of 1.0 to 3.5 V vs Li+/Li. The resulting electrochemical performance along with structural flexibility of perylene dianhydride (PTCDA) based polyimides cathode materials offers new approaches to develop high-performance all-organic LIBs.
