摘要： A method of manufacturing a porous electrolytic metal foil, in which a thin metal layer is formed by electrically depositing a metal on the surface of a cathode body by moving the cathode body through an electrolyte. The thin metal layer is separated from the cathode body to form an exposed surface on the cathode body and a film of an electrical insulating material is formed on the exposed surface of the cathode body, by spraying a resin liquid onto the exposed surface, or by suspending machine oil or insulating oil in the electrolyte. The metal foil thus produced has many open-pores in the thickness direction. Therefore, when the metal foil is used as a collector for a battery electrode, there is an improvement in the cycle life characteristics of the battery.
