A hierarchical porous carbon is fabricated by introducing a polyurethane sponge to a template graphene oxide into a 3D inter connected structure, while KOH activation generates abundant micropores in its backbone. Supercapacitors assembled with this carbon achieve a high energy density of 89 W h kg(-1) (64 W h L-1) and outstanding power density due to the shortened ion-transport distance in 3D.
