Abstract

Sandwich-like composite on the base of graphene and Co₃O₄ nanocubes is a prospect material for electrodes of chemical sources of current. The total capacitance of this material is mainly contributed by quantum capacitance that depends on a change of Fermi level during charge/recharge cycles. The main goal of this paper is to calculate the dependence of Co₃O₄@graphene’s quantum capacitance on mass ratio of its components. The obtained results can be applied in the design of modern supercapacitors and lithium-ion batteries.
