Abstract: A secondary battery includes an outer package member, a battery device, an electrode terminal, and an insulating member. The outer package member has a through hole. The battery device is contained inside the outer package member. The electrode terminal is disposed on an outer side of the outer package member and covers the through hole. The insulating member is disposed between the electrode terminal and the outer package member, and does not cover the through hole. The outer package member includes a container part having an opening and containing the battery device inside, and a cover part having the through hole and closing the opening. The container part and the cover part are joined to each other. The insulating member has a temperature of deflection under load ranging from 60° C. to 150° C. both inclusive. The cover part has a thickness smaller than a thickness of the container part.

Abstract: A secondary battery includes an outer package member, a battery device, an electrode terminal, and an adhesive member. The battery device is contained inside the outer package member. The electrode terminal is disposed on an outer side of the outer package member. The adhesive member has an insulating property and is disposed between the electrode terminal and the outer package member. The outer package member includes a container part and a cover part. The container part has an opening and contains the battery device inside. The cover part closes the opening and is joined to the container part. A portion or all of a peripheral end part of the electrode terminal is adhered to the cover part via the adhesive member. The electrode terminal has a thickness greater than a thickness of the cover part.

Abstract: A battery includes an outer package member, a battery device, a sealing member, and a terminal member. The outer package member has an outer diameter and a height. The battery device is contained inside the outer package member. The sealing member has an insulating property. The terminal member is supported by the outer package member via the sealing member. A ratio of the outer diameter to the height is greater than or equal to 0.1 and less than 1. The outer package member includes a container member and a cover member. The container member has an opening, and contains the battery device in an inside of the container member. The cover member is welded to the container member, closes the opening, and has a through hole. The terminal member is fixed to the cover member via the sealing member, and covers the through hole. A fixation strength of the terminal member to the cover member is lower than a welding strength of the cover member to the container member.

Abstract: A secondary battery includes an outer package member, an electrode terminal, a battery device, a first wiring line, and a second wiring line. The outer package member has a flat and columnar shape and includes a first bottom part and a second bottom part opposed to each other. The electrode terminal is provided on the first bottom part and is insulated from the first bottom part. The battery device is contained inside the outer package member and includes a first electrode and a second electrode. The first electrode and the second electrode are opposed to each other and are wound. The first wiring line is so coupled to the first electrode as to protrude from the battery device toward the first bottom part and is coupled to the electrode terminal. The second wiring line is so coupled to the second electrode as to protrude from the battery device toward the first bottom part and is coupled to the first bottom part.

Abstract: A secondary battery includes an outer package member, a battery device, and an insulating member. The outer package member has a flat and columnar shape and includes a first bottom part and a second bottom part opposed to each other. The battery device is contained inside the outer package member, and has a first through hole extending from the first bottom part toward the second bottom part. The insulating member is adhered in part to the battery device between the second bottom part and the battery device, and has a second through hole at a position overlapping with the first through hole.

Abstract: 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.
