Abstract

Spinels are not known for their supercapacitive nature. Here, we have explored electrochemically synthesized nanostructured NiCo₂O₄ spinel thin-film electrode for electrochemical supercapacitors. The nanostructured NiCo₂O₄ 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.
