Patent ID: 8166635

Claim:
A manufacturing method of an electrode provided with a perforated current collector, comprising: a current collector laminating step in which plural current-collector materials are laminated on either of both and any of the surfaces of a block layer so as to form a current-collector laminate unit; a protection layer formation step for forming a protection layer having a predetermined pattern on a front surface of the current-collector laminate unit; an etching step for performing an etching process on the current-collector laminate unit having the protection layer formed thereon so as to form through-holes on each of the current-collector materials; a first application step in which an electrode slurry is applied onto the front surface of the current-collector laminate unit on which the through-holes are formed; a current collector peeling step in which the current-collector material having the electrode slurry applied thereon is peeled from the current-collector laminate unit; and a second application step in which an electrode slurry is applied onto a back surface of the current-collector material peeled from the current-collector laminate unit.
