Document Type and Number:
WIPO Patent Application WO/2018/163775
Kind Code:
A1
Abstract:
One embodiment of the present invention relates to a production method for a secondary battery comprising an electrode assembled body 500 having a planar layered structure wherein a plurality of electrode-constituting layers 300 have been layered into a planar form, each containing a positive electrode 10A, a negative electrode 10B and a separator 50, as can be seen in a cross-sectional view. In particular, the one embodiment of the present invention comprises at least (i) a step of adhering, by following a layering direction, a separator 50 on at least one of the main surfaces of the negative electrode 10B, to form an electrode-constituting layer precursor 100α having the negative electrode 10B and the separator 50, and (ii) a step of cutting the electrode-constituting layer precursor 100α by following the layering direction.
