    摘要： Provided are a stepped battery and a method and device for manufacturing the stepped battery, and more particularly, a stepped battery and a method and device for manufacturing the stepped battery, which processes a tent part of a separation film formed on a stepped part of the stepped battery, to prevent a defect from occurring during a subsequent process. A stepped battery manufacturing method includes preparing a stepped battery (10) having a tent portion of a separation film (16) formed on at least one stepped surface (18), and pressing the tent portion by using a press tool (30) having a shape corresponding to the stepped surface (18) of the stepped battery (10).
