Spinels are not known for their supercapacitive nature. Here, we have explored electrochemically synthesized namostructured NiCo(2)O(4) spinel thin-film electrode for electrochemical supercapacitors. The nanostructured NiCo(2)O(4) spinel thin film exhibited a high specific capacitance value of 580 F g(-1) and an energy density of 32 Wh kg(-1) at the power density of 4 kW kg(-1), accompanying with good cyclic stability.
