Hierarchical NiCo₂O₄Nanosheets Grown on Ni Nanofoam as High-Performance Electrodes for Supercapacitors

A high-performance electrode for supercapacitors is designed and synthesized by growing electroactive NiCo2O4 nanosheets on conductive Ni nanofoam. Because of the structural advantages, the as-prepared [email protected]2O4 hybrid nanostructure exhibits significantly improved electrochemical performance with high capacitance, excellent rate capability, and good cycling stability.
