▎ 摘　　要

NOVELTY - The method involves forming a first graphene layer by chemical vapor deposition of graphene on one surface of a metal foam, and removing the metal foam. A metal layer is formed on a surface of the first graphene layer through a sputtering process. An intermediate material layer is prepared by the chemical vapor deposition. The intermediate material is calcined to form first and second porous graphene layers from the graphene layers. The metal foam is made of nickel, cobalt, iron, platinum, gold, silver, aluminum, chromium, copper, magnesium and manganese. The second active material layer is formed between the second porous graphene layer and the metal layer by hydrothermal reaction of metal layer and a mixed solution. Each of the first active material layer and the second active material layer is nickel dihydroxide, nickelic phosphide and trinickel disulfide. USE - The method is useful for manufacturing electrode for supercapacitor (all claimed). ADVANTAGE - The method enables manufacture of supercapacitor electrode having high power density, energy density, durability, structural stability and electrical properties, with high productivity and reduced cost. DESCRIPTION OF DRAWING(S) - The drawing shows a method for manufacturing an electrode for a supercapacitor (Drawing includes non-English language text).
