They are characterized by x-ray diffraction, scanning electron microscopy, density and surface area methods. The electrochemical properties were evaluated using cyclic voltammetry and galvanostatic cycling, in the cycling range, 0.005-3.0 V at room temperature. In this article, we studied the effect of different Co-salts on morphology and electrochemical properties. The observed reversible capacities (at a current rate of 60 mA g-1, at 40th cycle) of Co3O4 prepared by using Co-sulphate for 3 h; 15 h, Co-hydroxide and Co-acetate salts are 786; 707, 1080 and 916 (±5) mAh g-1, respectively. At a current of 600 mA g -1, it deliver a reversible capacity of 710 (±5) mAh g -1 (prepared using Co-hydroxide source), at the end of 50th cycle. © 2011 The Electrochemical Society.
