Nickel-cobalt oxide nano-flakes materials are successfully synthesized by a facile chemical co-precipitation method followed by a simple calcination process. The studies show that the as-prepared nickel-cobalt oxides with different Ni/Co ratio are composed of NiO and Co3O4 compounds. The Co0.56Ni0.44 oxide material, which exhibits a mesoporous structure with a narrow distribution of pore size from 2 to 7 nm, possesses markedly enhanced charge-discharge properties at high current density compared with the pure NiO and pure Co3O4. The Co0.56Ni0.44 oxide electrode shows a specific capacitance value of 1227 F/g at 5 mA/cm2, which is nearly three times greater than that of the pure NiO electrode at the same current density.
