▎ 摘　　要

NOVELTY - A zinc-cobalt oxide electrode material comprises graphene hollow microspheres, cobalt(II) chloride, zinc chloride, nickel(II) chloride, reducing agent, ammonium fluoride, and urea in mass ratio of (0.08-0.15):(1.8-2):1:(0.03-0.05):(1.4-1.8):(0.3-0.5):(2-3). USE - Zinc-cobalt oxide electrode material for supercapacitor. ADVANTAGE - The zinc-cobalt oxide electrode material has increased specific surface area, excellent wettability, thereby exposing a large number of electrochemically active sites, enhanced electrical conductivity, and excellent specific capacitance and electrochemical cycle stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the zinc-cobalt oxide electrode material.
