Method for producing electrode
Abstract:
A main object of the present disclosure is to provide a method for producing an electrode of which uncoated part can stretch while inhibiting breakage. The present disclosure achieves the object by providing a method for producing an electrode, the method including: a preparing step of preparing a precursor sheet including a metal foil, and a coated part and an uncoated part, arranged on the metal foil; a coated part pressing step of pressing the coated part in a thickness direction; and an uncoated part pressing step of pressing the uncoated part in the thickness direction, before or after the coated part pressing step; wherein the coated part contains an electrode material including at least an active material; the uncoated part does not contain the electrode material, and is arranged in an edge of the coated part; and in the uncoated part pressing step, the uncoated part is roll-pressed by a pair of an elastic roll including a shaft body and an elastic body covering the shaft body, while the uncoated part is pushed against the thickness direction.
