    Abstract: A secondary battery includes an electrode body that includes a positive-electrode sheet and a negative-electrode sheet, an exterior body that accommodates the electrode body, a sealing plate that seals an opening of the exterior body, a positive-electrode terminal that is secured to the sealing plate, a positive-electrode tab that is connected to the positive-electrode sheet, a first positive-electrode current collector that is connected to the positive-electrode terminal and electrically connected to the positive-electrode tab, an inner insulating member that is disposed between the sealing plate and the first positive-electrode current collector, and a cover that is composed of a resin and disposed between the first positive-electrode current collector and the electrode body. The cover includes a cover portion that faces the first positive-electrode current collector and a cover joint that extends from the cover portion toward the sealing plate. The cover joint is connected to the inner insulating member.

    Abstract: A sealed battery includes an electrode assembly; a case having an opening portion and accommodating the electrode assembly; a lid closing the opening portion and having a through-hole; a collector terminal including an inner terminal segment and a projection; and an insulating seal in contact with a bottom surface of the lid, the bottom surface being an inner side of the lid in a thickness direction of the lid, the inner side of the lid facing an inside of the case when the lid closes the opening portion, and the insulating seal providing sealing between the lid and the collector terminal. The lid has a protrusion protruding from the bottom surface of the lid. The protrusion surrounds the through-hole. A part of the protrusion protrudes into the through-hole. The through-hole has a smallest opening diameter at a position at which the part of the protrusion protrudes into the through-hole.

    Abstract: A square secondary battery includes an electrode body including a positive electrode plate and a negative electrode plate, a square outer package housing the electrode body, a metal sealing plate sealing an opening of the square outer package, and a positive electrode collector electrically connected to the positive electrode plate and the sealing plate. The positive electrode collector includes a base portion disposed to oppose the sealing plate, and a lead portion extending from an edge portion of the base portion towards the electrode body. In a short direction of the sealing plate, a boundary between the base portion and the lead portion is positioned on a first side with respect to a center of the sealing plate, and a connection between the sealing plate and the base portion of the positive electrode collector is offset to a second side with respect to the center of the sealing plate.
