摘要：A process for preparing a porous electrolytic metal foil by electrodepositing ametal on a drum cathode by using a drum cathode and an anode to form a metal foillayer and separating the formed layer from the drum cathode, wherein a coating of anelectrically insulating material is formed on the cathode surface exposed after the foilseparation by subjecting the exposed surface to electrolytic oxidation, by spraying theexposed surface with a resin liquid, or by suspending a machine oil or the like in anelectrolyte to deposit the machine oil onto the exposed surface. The metal foil thusobtained has a large number of interconnecting pores in the direction of thickness and,when used as a collector substrate of an electrode for a battery, can prevent the

separation of a composite for a battery, thus contributing to an improvement in the cycletime of a battery.
