Outline of Final Research Achievements

Electrochemical capacitor electrodes were made of nickel oxides, nickel hydroxides and carbon nanotubes (CNT). Electrophoretic deposition of CNT onto stainless steel substrate was conducted to form CNT membrane. Formed CNT membrane was then decorated with nickel nanoparticles using pulse electroplating technique, which was followed by annealing in air for oxidation of the nickel. Electrochemical measurement of the CNT/NiOx electrodes revealed that the higher capacitance is achieved by the final moderate annealing which prevents the coarsening of Ni-species particles and promotes oxidatin of nickel to form nickel oxides.
