Dihydrophenazine linked porous organic polymers for high capacitance and energy density pseudocapacitive electrodes and devices

Abstract

Redox porous organic polymers are promising pseudocapacitive materials. However, their specific capacitance still needs further elevation. Herein, we report a novel dihydrophenazine derived porous organic polymer, GT-POP-1. The GT-POP-1 based electrode and asymmetric device show high specific capacitance and energy density metrics of 97.1 mF cm⁻² and 7.3 μW h cm⁻².
