Facile synthesis of a nano-structured nickel oxide electrode with outstanding…

Abstract. A superior electrode for high-performance supercapacitors has been designed by growing homogeneous NiO nanoparticles on conductive Ni foam substrate through a facile two-step method. The preparation strategy involves the electrodeposition of nickel hydroxide precursor on Ni foam and subsequent low temperature annealing process. These NiO nanoparticles are interconnected with each …
