METHOD FOR MANUFACTURING ELECTRICITY-STORAGE DEVICE, AND ELECTRICITY-STORAGE DEVICE

摘要

A method for producing an electrical storage device (100) includes winding a positive electrode (40), a negative electrode (50), and a lithium ion source (30) to form a wound element (20) that has a flat part (22) and a curved part (24), the lithium ion source (30) including a plurality of parts (32, 34) that are arranged in a winding direction through a gap (36), the wound element (20) being formed so that the gap (36) is situated in the curved part (24).
