Hierarchical porous heteroatom-doped carbon materials are one of the most promising for supercapacitor (SC) electrodes due to their outstanding inherent characteristics. In this study, a micro/mesoporous N, P, S-tridoped material (NPSC-900) is prepared using poly(cyclotriphosphazene-co-4,4′-sulfonyldiphenol) as only precursor through one-step synthesis strategy combining direct carbonization and in situ heteroatom doping. The obtained NPSC-900 SC electrode exhibits electrochemical performances, such high capacitance 392 F g–1 at 2 mV s–1, superior rate capacity, good long-term stability after 10,000 cycles with 98.5% retention. Moreover, flexible asymmetric assembled by coupling NSPC-900/carbon cloth (CC) NiO/CC electrodes. Its maximum energy power densities reach 119.5 Wh kg–1 23.4 kW kg–1, respectively. remarkable properties NSPC-900 benefited from adequate surface area, ultralarge pore volume, hierarchical structure, skeleton, which provide significant way designing high-performance storage systems.
