▎ 摘　　要

NOVELTY - A mixed-type supercapacitor comprises an anode aluminum foil, a cathode aluminum foil, an electrolyte and a separator. Both sides of cathode aluminum foil are coated with cathode material obtained by mixing 85-92 %mass activated carbon, 4-10 %mass conductive agent, 1-2 %mass dispersant and 3-10 %mass binder. Both sides of anode aluminum foil are coated with anode material obtained by mixing 80-92 %mass lithium titanate/graphene composite material, 4-10 %mass conductive agent and 4-10 %mass binder. USE - Mixed-type supercapacitor (claimed). ADVANTAGE - The mixed-type supercapacitor has rapid charging and discharging characteristics, and high energy density, capacity and circulation stability.
