  • Patent number: 12002942
    Abstract: A method for manufacturing a rechargeable battery includes forming a mixture layer and an insulating layer on an electrode substrate having an edge extending in a specified direction so that an exposed portion where the electrode substrate is exposed extends between the edge and the insulating layer; pressing the mixture layer; and stretching an extension portion, located between the edge and the mixture layer, and the insulating layer in the specified direction. The stretching includes applying a stress greater than or equal to yield stress of the electrode substrate or greater than or equal to 0.2% proof stress of the electrode substrate and less than tensile strength of the electrode substrate to the extension portion, and applying a stress greater than or equal to yield stress of the insulating layer or greater than or equal to 0.2% proof stress of the insulating layer to the insulating layer.
