High mass loading and high-density flower-like NiCo2O4 nanosheets on Ni foam for superior capacitance

Abstract

We report a simple route for high-density flower-like NiCo2O4 nanosheets with ultrahigh mass loading of 9.2 mg cm−2 on nickel foam to achieve superior capacitance. The as-assembled asymmetric supercapacitor yields a high energy density of 87.4 W h kg−1 and an excellent cycle life with 93.2% capacitance retention after 11 000 cycles.
