A high performance asymmetric electrochemical supercapacitor with a mass loading of 10 mg cm-2 on each planar electrode is fabricated by using graphene-nickel cobaltite nanocomposite  as a positive electrode and commercial activated carbon  as a negative electrode. The capacitor exhibits favorable energy and power densities, and 102% capacitance retention at over 10,000 cycles.
