Abstract: The present invention relates to a method of manufacturing a cathode electrode for a secondary lithium battery using vanadium oxide. Vanadium oxide is dissolved in an aqueous solution containing H2O2 to form a gel. Thus, the gel can be applied to a metal support even when the binder is not used or the binder of a small amount is used. If vanadium oxide of an adequate amount is put into the aqueous solution containing. H2O2, a transparent aqueous solution is formed while oxygen is generated. The aqueous solution is then changed to a gel state of a viscosity as the time elapses. A small amount of a conductive material and a binder are added in the course that the gel is formed, and are then uniformly mixed with vanadium oxide being an active material, so that a slurry is formed. As the slurry has a high viscosity, it can be applied to the metal support even with a small amount of the binder. Further, as the conductive material, the binder, etc.
