摘要： A blended solution is made by melting LiOH.H2O into distilled water, and then, Co metallic powders are added into the blended solution to make a reactive solution. The reactive solution is charged into an autoclave, and held at a predetermined temperature. Then, a pair of platinum electrodes are set into the reactive solution, and a given voltage is applied between the pair of platinum electrode. As a result, a compound thin film, made of crystal LiCoO2 including Li element of the blended solution and Co element of the Co metallic powders, is synthesized on the platinum electrode constituting the anode electrode.
