METHOD OF PREPARING DRY ELECTRODE

A method of preparing a dry electrode includes arranging at least one interlayer on at least one surface of an electrode current collector to prepare a first stack, arranging a dry electrode film, which has an area larger than an area of the interlayer, on the first stack to prepare a second stack, 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 and provide a dry electrode, wherein the dry electrode film has anisotropic tensile strength, and the dry electrode includes a dry electrode active material layer on the interlayer, but the dry electrode active material layer disposed directly on the electrode current collector is absent.
