Abstract
Supercapacitor is an energy storage device with high power density and low energy density, and is normally used with a battery to satisfy one's needs for high power density and high energy density. The present invention provides a method to fabricate a novel battery type supercapacitor, with a multi-layered structure composed of a plurality of thin layers which is formed by alternately stacking high specific energy battery material and/or supercapacitor material such as metal oxides, metal hydroxides, metal sulfides, conductive polymers, carbon materials with reduced graphene oxide (rGO), to obtain a supercapacitor with both high specific energy density and high specific power density. Such a novel multi-layered structure composed of a plurality of thin layers formed by alternately stacking battery or capacitor material and rGO can not only ensure the obtained electrode to greatly improve the diffusion control of reaction particles, but also enhance its kinetic characteristic, so as to achieve both high power density and high energy density when used as a capacitor.
