Title:
METHOD OF MANUFACTURING SECONDARY BATTERY, AND SECONDARY BATTERY
Document Type and Number:
Japanese Patent JP2016091664
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method of manufacturing a secondary battery having a lamination type electrode body in which peeling-off of electrode plates is not caused by winding a fixing tape.SOLUTION: In a fixing process, a fixing tape is wound from the outside of an electrode body on the first side face of the electrode and the second side face forming the rear face of the first side face over the tops of the first end face and the second end face at both ends in the lamination direction of the electrode body. In a lamination process prior to the fixing process, the electrode body is formed, and a protective member for protecting a corner on the downstream side in the winding direction of the fixing tape on the first and second side face of the electrode body is at least disposed at the corner.SELECTED DRAWING: Figure 2
