[Solution] The positive electrode tab and negative electrode tab are both disposed at the beginning side of a winding for wound electrodes. An outer housing and sealing plate are welded in a state with the positive electrode tab sandwiched at a mating part of the outer housing and sealing plate. The negative electrode tab is electrically connected to a negative electrode terminal provided on the sealing plate. The positive electrode tab and negative electrode tab are divided by a space of 2-12 mm in the direction of battery width.

摘要： In a prismatic secondary battery, an internal negative electrode terminal is electrically connected to a collector through through-holes formed in a sealing plate, a gasket, and an insulating member in a manner electrically insulated from the sealing plate. The sealing plate has one face on which a protrusion is formed, an insulating plate has a face that is on the sealing plate and on which a concave portion fitted to the protrusion is formed, each of the protrusion and the concave portion of the insulating plate is provided at one position on respective sides of the through-hole, and at least one of the protrusions has a top face on which a concave portion is formed. The battery having such a structure is unlikely to cause rotary displacement between the insulating plate and the sealing plate even when a rotary torque is applied to the internal terminal.

摘要： A prismatic secondary battery includes a prismatic hollow outer body having a mouth and a bottom; a flat electrode assembly, a positive electrode collector, a negative electrode collector, and an electrolyte, all of which are stored in the prismatic outer body; a sealing plate sealing up the mouth of the prismatic outer body; and a positive electrode terminal attached to the sealing plate in an electrically insulated manner. The sealing plate includes a gas release valve and an electrolyte pour hole and further includes, on the front face, a concaved flat face having an identification code. With the prismatic secondary battery of the invention, a jig for assembly or the like is unlikely to come into contact with the identification code during an assembly process of the prismatic secondary battery, hence the identification code is unlikely to be abraded, and the traceability is unlikely to be lost.
