Zusammenfassung: | Provided are a dry electrode, a method for manufacturing the dry electrode, and a lithium battery including the dry electrode, the method comprising the steps of: providing one or more intermediate layers on one side or both opposite sides of an electrode current collector to prepare a first laminate; preparing a second laminate by disposing a dry electrode film having an area larger than an area of the intermediate layer on the first laminate, in which the dry electrode film includes a first region on the intermediate layer and a second region extending from the first region beyond an outer periphery of the intermediate layer; and dragging out at least a portion of the second region of the dry electrode film to separate the second region from the first region, thereby disposing the dry electrode, the intermediate layer including a peripheral region and an intermediate region, in which a thickness of the peripheral region is greater than a thickness of the intermediate region.
