POROUS CURRENT COLLECTOR FOR BATTERY, ELECTRODE, THEIR PRODUCTION AND APPARATUS FOR PRODUCTION THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide an apparatus and method capable of inexpensively producing a long-sized porous metallic band and electrode suitable for production of current collectors and electrodes for batteries and the porous metallic band and electrode produced by the same. SOLUTION: A conductive drum 12 formed by providing the outer peripheral surface consisting of a conductor part 10 with nonconductor parts 11 in prescribed patterns is immersed into a plating bath 14 and a porous plating layer 15 is formed on the outer peripheral surface of the conductive drum 12 by rotating the conductive drum 12. The conductive drum 12 is further rotated to take the porous plating layer 15 out of the plating bath 14 in the state of keeping the plating layer adhered to the outer peripheral surface. The plating layer is then peeled from the outer peripheral surface by means of a peeling positioning roll 19 and a pair of peeling angle regulating rolls 20, 21 after cooling and is thereafter washed, by which the porous metallic band 15a is produced.
