▎ 摘　　要

NOVELTY - Manufacturing a porous electrode involves a first electroplating with a transition metal on the substrate, and performing a second electroplating of the transition metal-plated substrate. USE - Manufacturing porous electrode used in supercapacitor (claimed). ADVANTAGE - The method enables to manufacture porous electrode having excellent energy storage capacity and energy storage performance by including a two-dimensional structure including a porous structure and a network structure at the same time to increase the electrochemical reaction area. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a cathode comprises the porous electrode, anode, and an electrolyte filled between the cathode and the anode Including, supercapacitors.
