Document Type and Number:
WIPO Patent Application WO/2018/173700
Kind Code:
A1
Abstract:
A secondary battery manufacturing method and manufacturing device are provided which, in the case that a secondary battery precursor has a stepped portion, can apply a voltage not only to the topmost step of the secondary battery precursor, but also to steps other than the topmost step. This invention relates to a secondary battery manufacturing method and manufacturing device in which an electrolyte and an electrode assembly, including a positive electrode, a negative electrode and a separator arranged between the positive electrode and the negative electrode are sealed in an outer casing, and the secondary battery precursor, having a stepped portion, is pressed using a pressing member having a pressing surface corresponding to the stepped shape of the stepped portion.
