标题：high volumetric capacitance, ultralong life supercapacitors enabled by waxberry-derived hierarchical porous carbon materials

abstact：supercapacitors with fast charge/discharge rate and long cycling stability (>50 000 cycles) are attractive for energy storage and mobile power supply. in this paper, a facile strategy is developed to fabricate an fe2o3/fes-decorated n, s-codoped hierarchical porous carbon hybrid. its microstructure and compositions can be readily controlled through adjusting the hydrothermal reaction between waxberry and iron sulfate. the constructed supercapacitors with the as-prepared carbon materials from this reaction are able to exhibit outstanding capacitive performance with a superfast charge/discharge rate (<1 s), ultralong cycle life (>50 000 cycles, 80 a g−1), ultrahigh volumetric capacitance (1320.4 f cm−3, 0.1 a g−1), and high energy density (100.9 w h kg−1, 21.9 w h l−1). the outstanding performance makes it one of the best iomass-derived supercapacitors. the superior capacitive behavior is likely to rise from the n and s codoping on the surface/edge/skeleton of the carbon microspheres and nanosheet composites coupled with the fast redox reaction f fe2o3/fes. overall, this research presents a new avenue for developing the ext generation of sustainable high-performance energy storage device..
