Free-standing porous carbon nanofiber membranes obtained by one-step carbonization and activation for high-performance supercapacitors

The capacitive performances of carbon materials greatly rely on the porous structure and conductive network. However, the compromise of carbon materials with suitable porosity and 3D conductive framework still exists difficulty. Herein, a hierarchical porous free-standing carbon nanofiber (CNF) membrane was obtained from electrospun cellulose acetate (CA) nanofiber membrane via one-step carbonization and activation process. The influence of...
