    Abstract: A flat-shaped winding electrode body in which a positive electrode plate and a negative electrode plate are wound with a separator interposed therebetween includes a positive electrode tab portion and a negative electrode tab portion at one end in a direction in which a winding axis of the winding electrode body extends. Two pieces of the flat-shaped winding electrode body are housed in a prismatic outer body so that the winding axis of each piece is disposed in a direction perpendicular to a sealing plate, and the positive electrode tab portion and the negative electrode tab portion are located on one end of the winding electrode body closer to the sealing plate than the other end.

    Abstract: A prismatic secondary battery includes an electrode body including a positive-electrode sheet and a negative-electrode sheet, a prismatic exterior body that accommodates the electrode body, a sealing plate that seals an opening of the prismatic exterior body, and a negative terminal electrically connected to the negative-electrode sheet. The positive-electrode sheet is electrically connected to the sealing plate. The sealing plate has a recessed portion on an outer surface and a terminal insertion hole formed in the recessed portion. The negative terminal is inserted in the terminal insertion hole. An outer insulating member is disposed between the negative terminal and the sealing plate. The sealing plate has a first groove extending to an end of the recessed portion in the longitudinal direction of the sealing plate.

    Abstract: A negative electrode terminal includes a flange, and a connection portion disposed on a first surface of the flange. The connection portion is inserted into a terminal attachment hole. The negative electrode terminal includes a first area made of aluminium or an aluminium alloy, and a second area made of copper or a copper alloy. In the flange, the second area is disposed adjacent to the first surface, and the first area is disposed adjacent to the second surface. A boundary between the first area and the second area is disposed between the first surface and the second surface. A thinnest portion of the first area of the flange in the thickness direction of the flange has a thickness of larger than or equal to 0.3 mm. An external electroconductive member made of aluminium or an aluminium alloy is welded to the flange to form a welded portion.
