A secondary battery includes a battery device, a container member, a cover member, and an electrode terminal. The battery device includes a positive electrode and a negative electrode. The container member contains the battery device inside. The cover member is welded to the container member. The electrode terminal is provided in the cover member. The cover member includes a recessed part formed by the cover member bending to protrude in part toward the inside of the container member. The electrode terminal is disposed inside the recessed part.

A secondary battery includes an outer package member, a battery device, a positive electrode terminal, a negative electrode terminal, and a fixing member. The outer package member has flexibility. The battery device has an elongated shape, and is contained inside the outer package member. The battery device includes a positive electrode and a negative electrode. The positive electrode terminal is coupled to the positive electrode, and is led out to an outside of the outer package member. The negative electrode terminal is coupled to the negative electrode, and is led out to the outside of the outer package member. The fixing member is disposed between the outer package member and the battery device, and is adhered to each of the outer package member and the battery device. The positive electrode and the negative electrode are opposed to each other and are wound in a first direction.

The disclosure relates to the technical field of batteries, and proposes a battery and a battery apparatus. The battery includes: a housing; a cell, the cell disposed in the housing. A pole element is disposed on the housing. A heat sink is disposed on the housing.

The disclosure relates to the technical field of batteries, and provides a battery, a battery apparatus and a battery pack. The battery includes a battery surface and a pole element. The battery surface is provided with a first recess, and the first recess is used to accommodate the pole element of the other battery. The pole element is arranged on the battery surface and is located outside a range where the first recess is located. By providing the first recess on the battery surface, the pole element of the other battery can be accommodated in the first recess when the batteries are grouped.

The disclosure provides a battery, a battery module, a battery pack, and a battery manufacturing method. The battery includes a housing, a cell, a pole assembly and a connecting piece. The housing includes two first surfaces opposite to each other in a first direction. The cell is arranged in the housing and includes a cell body and a tab portion. The tab portion includes two or more single-piece tabs extending from the lateral side of the cell body. The pole assembly is arranged on the first surface, and the tab portion and the pole assembly are connected through the connecting piece. The vertical distance between an end of the tab portion away from the lateral side of the cell body and the lateral side of the cell body is smaller than the vertical distance between the pole assembly and lateral side of the cell body.

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.

An electricity storage device has an electricity storage element sealed in a package member of a laminate material including a thermal adhesive resin layer. The package member has a housing portion having a substantially rectangular opening and formed to have a predetermined depth; a flange portion protruding outward from the circumferential edge of the opening; and a lid portion covering the opening and thermally bonded to the flange portion. The electricity storage element has a pair of electrode terminals protruding respectively from opposite longer-side edges of the opening and held between the flange portion and the lid portion.
