We report nickel oxide (NiO) fine nanoparticles with an average diameter of 5.3 ± 1.3 nm as an electrode material for supercapacitor reactions. The superior pseudocapacitive behavior of NiO nanoparticles was demonstrated in three-electrode half-cells and two-electrode button cells, with a maximum sp...
