MANUFACTURING METHOD FOR SECONDARY BATTERY

Document Type and Number:

Japanese Patent JP2017228349

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a manufacturing method for a secondary battery, which prevents wrinkling of widthwise both side edges, orthogonal to a longitudinal direction, of an electrode sheet in which plied timber is uncoated.SOLUTION: A manufacturing method for a secondary battery comprises: a drawing step 10 in which an electrode sheet 15, in which a plied timber 15c with 80% or more solid content concentration is coated except widthwise both ends orthogonal to a longitudinal direction, is heated and conveyed while uncoated both side edges 15b of the plied timber 15c are drawn by a recessed and projecting roll 14; and a press step 17 in which the electrode sheet 15, in which uncoated both side edges 15b of the plied timber 15c are drawn by the drawing step 10, is pressed.SELECTED DRAWING: Figure 1
