A long-life pseudocapacitive triazine-based porous organic framework and resulting N-doped microporous carbons for supercapacitance application

Abstract

A porous organic framework as electrode material for supercapacitor was prepared successfully. It exhibited the remarkable specific capacitance of [Formula: see text] at current density of [Formula: see text], and 100% of capacitance retention after successive charge–discharge 10,000 cycles in an alkaline aqueous electrolyte solution. At the same time, we explored the electrochemical performance of porous N-doped carbon derived from the template of porous organic framework as supercapacitor electrode material. Impressively, it possessed the higher specific capacitance and better cycling stability, which showed specific capacitance of [Formula: see text] at the current density of [Formula: see text] and retained 100% of initial capacitance after 30,000 cycles.
