▎ 摘　　要

NOVELTY - A super capacitor comprises an electrode, a diaphragm, an electrolyte, an electrolyte membrane, and an electrode on the outer side of the electrolyte. The electrode is obtained by coating mixture of inorganic nano particles (2-10 %mass), manganese dioxide nano material (40-78 %mass) and graphene (12-58 %mass) on a substrate surface. USE - Super capacitor. ADVANTAGE - The super capacitor has high thermal conductivity, mechanical property, and specific capacitance.
