Ni/NiO sphere-like composites as high-performance supercapacitor electrodes: insights into redox processes at negative potentials

Nishanth Sudarsanan, Akshaya Perumal, M. Jayachandran, S. Kishore Babu, T. Vijayakumar

The Ni reduces at −350 mV (negative CV region), while reversible redox occurs at positive potentials. The NiO structure, capacitance retention over 10 000 cycles, and redox equation are shown.
