Короткий огляд (реферат): | ABSTRACT The simple and effective hydrothermal synthesis of spherical α-Ni(OH)2 particles and α-Ni(OH)2 / carbon composites was proposed. The mechanism of ultrafine α-Ni(OH)2 phase forming and correlations between synthesis conditions, morphology, electrical conductivity were analyzed. It was found that carbon nanoparticles form electric conductive covering on nickel hydroxide microparticles during synthesis that increases overall electronic conductivity of composite material. α-Ni(OH)2 and α-Ni(OH)2 / C samples were tested as electrodes for hybrid supercapacitors. It was found that carbon coverings stabilize α-Ni(OH)2 phase in the alkaline medium. The comparison of laser irradiation and ultrasonic treatment influence on the electrochemical performance of the obtained materials was made. |
