ABSTRACT:
The present invention provides an electrode plate for a secondary battery with a nonaqueous electrolyte, and a process for producing same capable of forming accurately and economically the active material layer on the collector surface. The process comprises the steps of: (1) applying a peelable material on a predetermined area of a collector surface, and drying same to form a peelable layer; (2) applying an electrode forming composition comprising an active material and a binder on the collector surface to form an active material layer lying over at least one area of the peelable layer previously formed; and (3) peeling the peelable layer from a collector together with a portion of the active material layer disposed on the peelable layer to partially expose the collector surface, thereby forming a noncoated portion having a predetermined pattern on the collector surface.
