Abstract
A method of manufacturing a wound electrode body by holding a first separator sheet between a pair of electrode sheets formed of a negative sheet and a positive sheet, laminating a second separator sheet in an outside of the pair of electrode sheets, and winding the pair of electrode sheets and the first and second separator sheets onto an outer circumferential surface of a winding core is provided. Before at least one electrode sheet of the pair of electrode sheets is attached to the winding core, a first fold line extended in a longitudinal direction of the one electrode sheet is formed in a leading part of the one electrode sheet.

A method of manufacturing a wound electrode body by holding a first separator sheet between a pair of electrode sheets formed of a negative sheet and a positive sheet, laminating a second separator sheet in an outside of the pair of electrode sheets, and winding the pair of electrode sheets and the first and second separator sheets onto an outer circumferential surface of a winding core, the method comprising:
- forming a first fold line that is extended in a longitudinal direction of at least one of the pair of electrode sheets in a leading part of the at least one of the pair of electrode sheets before the at least one of the pair of electrode sheets is attached to the winding core.
A method of manufacturing a wound electrode body by holding a first separator sheet between a pair of electrode sheets formed of a negative sheet and a positive sheet, laminating a second separator sheet in an outside of the pair of electrode sheets, and winding the pair of electrode sheets and the first and second separator sheets onto an outer circumferential surface of a winding core, the method comprising:
- forming a fold line that is extended obliquely from at least one corner part of a leading part to a center line of at least one of the pair of electrode sheets in the leading part of the at least one of the pair of electrode sheets before the at least one of the pair of electrode sheets is attached to the winding core.
