WIPO Patent Application WO/2018/173701
Kind Code:
A1
Abstract:
A secondary battery manufacturing method and manufacturing device are provided which, in the case that an electrode assembly precursor has a stepped portion, can apply a voltage not only to the topmost step of the electrode assembly precursor, but also to steps other than the topmost step. This invention relates to a secondary battery manufacturing method and manufacturing device in which a positive electrode and a negative electrode are arranged in an alternating fashion with a separator interposed therebetween, and an electrode assembly precursor 1 having a stepped portion 10 is pressed using a pressing member 3 having a pressing surface 3a corresponding to the stepped shape of the stepped portion 10, to obtain an electrode assembly.
