Title:
MANUFACTURING METHOD OF BATTERY
Document Type and Number:
Japanese Patent JP2017098040
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing method of a battery capable of shortening the time required for a temperature rise step in which a temperature of a plurality of non-sealed batteries alternately laminated and restricted via an interposing member is made rise.SOLUTION: A manufacturing method of a battery 1 includes the steps of: placing a restriction body 150 of a plurality of batteries 1x and an interposing member 110 on a heater 210 including a heating surface 210a on which a plurality of suction holes 210h are opened in such a manner that battery bottoms 10b are positioned on the suction holes 210h and that a member bottom 113b is abutted to the heating surface 210a; sucking air AR via the suction holes 210h and making a temperature of the interposing member 110 and the batteries 1c rise via the heating surface 210a while circulating the air AR also through a gap SK between the heating surface 210a and the member bottom 113b; and reducing a pressure within the batteries 1x of which the temperature has been made rise, and drying the inside of the batteries.SELECTED DRAWING: Figure 6
