A high‐performance electrode for supercapacitors is designed and synthesized by growing electroactive NiCo 2 O 4 nanosheets on conductive Ni nanofoam. Because of the structural advantages, the as‐prepared Ni@NiCo 2 O 4 hybrid nanostructure exhibits significantly improved electrochemical performance with high capacitance, excellent rate capability, and good cycling stability.
