High energy density supercapacitors composed of nickel cobalt oxide nanosheets on nanoporous carbon nanoarchitectures

Journal Article


Abstract


  • Porous carbon-metal oxide hybrid materials are advanced functional composites with great potential for use in high energy den sity supercapacitors. Here we describe a hybrid structure composed of two-dimensional (2D) NiCo 2 O 4 nanosheets synthesized on polyhedral-shaped nanoporous carbon (NC) particles. The NC particles were derived from the carbonization of zeolitic imidazole frameworks (ZIF-8). Supercapacitor devices assembled using NiCo 2 O 4 -NC nanoparticles had excellent capacitive properties with energy densities up to 28 W h kg -1 and power densities up to 8.5 kW kg -1 .
