DRY ELECTRODE, METHOD FOR MANUFACTURING DRY ELECTRODE, AND LITHIUM BATTERY INCLUDING THE DRY ELECTRODE

Abstract: provided is a method for manufacturing a dry electrode, the method including providing one or more interlayers on one side or two opposing sides of an electrode current collector to prepare a first laminate, preparing a second laminate by providing, on the first laminate, a dry electrode film having a larger area than the area of the interlayer, wherein the dry electrode film includes a first region on the interlayer, and a second region extending from the first region beyond an outer periphery of the interlayer, and pulling at least a portion of the second region of the dry electrode film to separate the second region from the first region, thereby providing a dry electrode, the interlayer includes: an outer peripheral region and an inter-region, wherein a thickness of the outer peripheral region is greater than a thickness of the inter-region.
