Abstract
Provided is a high capacity energy storage capacitor including: a cathode; and an anode arranged to face the cathode, wherein the cathode includes a current collector and a cathode material layer formed by applying a cathode material on one side or the other side of the current collector, and the anode includes a current collector an anode material layer formed by applying an anode material on one side or the other side of the current collector, wherein the cathode material is formed by mixing 70 to 99 wt % of nano-perforated graphene coating cathode active material and 1 to 30 wt % of nano-perforated graphene granular body, and the anode material is formed by mixing 70 to 95 wt % of nano-perforated graphene coating anode active material and 5 to 30 wt % of nano-perforated graphene granular body.
