Abstract
Carbon nanosheets fabricated by carbonization and activation or by carbonization alone. The nanosheets possess a disordered structure for copious reversible binding of ions at the carbon defects. They are also hierarchically micro-meso-macro porous, allowing facile ion transport at high rates both through the pore-filling electrolyte and in the solid-state. Also, a combined battery—supercapacitor energy storage device using the carbon nanosheets as one or both of the electrodes therein. Tuning the mass-loading ratio of the carbon nanosheets in the two electrodes configures the carbon nanosheets to operate either as a bulk insertion electrode (anode) or a surface adsorption electrode (cathode). The energy storage device may further include a housing with a form factor of a commercial battery.
