STEPPED BATTERY, AND METHOD AND APPARATUS FOR MANUFACTURING SAME

摘要

The present invention relates to a stepped battery, and a method and an apparatus for manufacturing same, and more specifically, to a stepped battery, and a method and an apparatus for manufacturing same, for preventing in advance defects from occurring in follow-up steps by treating a tent part of a separation film which is formed on a stepped portion of the stepped battery. The method for manufacturing a stepped battery, according to the present invention, comprises the steps of: preparing a stepped battery (10) having a tent part on a separation film (16) which has been formed on at least one stepped surface (18); and pressing the tent part using a press tool (30) having a shape corresponding to the stepped surface (18) of the stepped battery (10).
