▎ 摘　　要

NOVELTY - Nickel (II) hydroxide or nickel oxide nano particles wall super capacitor electrode comprises graphene nano wall array, collector and nickel (II) hydroxide or nickel oxide nano particles. The nickel (II) hydroxide/nickel nanoparticles are grown on the graphene nano-wall array and the graphene nano wall are vertically grown on the current collector. USE - Nickel (II) hydroxide/nickel oxide nano particles wall super capacitor electrode (claimed). ADVANTAGE - The nickel (II) hydroxide/nickel oxide nano particles wall super capacitor electrode is prepared economically by a simple process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation nickel (II) hydroxide/nickel oxide nano particles wall super capacitor electrode.
