  • Publication number: 20220367905
    Abstract: A manufacturing apparatus of a power storage device includes a resin filling mold configured to form an internal space that houses a laminated electrode body and to supply photo-curing resin used for forming a resin layer on at least a side surface on a long side of the laminated electrode body. The mold includes an upper mold, a lower mold, and two side surface molds on the long sides. Further, the manufacturing apparatus includes a light radiation device that radiates light which photo-cures the photo-curing resin supplied to the internal space. The manufacturing apparatus is configured to, when a front part of the supplied photo-curing resin that flows along the side surface reaches a predetermined position of the side surface, cure the flowing front parts by radiating the light from the light radiation device and stop the flowing front part from flowing along the side surface.
