1524985 Electrolytic perforation of metal foil INCO EUROPE Ltd 24 Aug 1976 [26 Aug 1975] 35178/75 Heading C7B An anodically polarized continuous metal foil is perforated in an electrolytic bath, one face contracting an inert endless surface e.g. a Ti or rubber surfaced roll or band, and the other contacting a perforated Ti band mask which may be pressed against the foil by an adjustable or sprung roller. A curved hollow and perforated cathode may be supplied internally with electrolyte which may be filtered or ion-exchanged in a recycle line. Ni, Cu or Fe may be so formed into battery electrodes.
