In this work, Al-substituted a-Co(OH)2/GO composites with supercapacitive properties were prepared by chemical co-precipitated method in which cobalt nitrate and aluminum nitrate were used as the raw material, and g...
Cobalt hydroxide, often used as an additive in nickel electrode, is rarely studied as active material for supercapacitors. In this paper, the Co(OH)2 with the particle size less than 20nm by deposition transformation ...
