摘要： An object of the present invention is to provide a high-output prismatic secondary cell that excels in current collecting efficiency and provides for reliable and highly productive welding with a lower welding current at the time of resistive welding of a current collecting plate onto a core exposed portion of a flat electrode assembly having at both ends a positive electrode core and a negative electrode core. This object is realized by a prismatic secondary cell including: a flat electrode assembly comprising a plurality of first electrode cores and a plurality of second electrode cores, the first electrode cores protruding from one end of the flat electrode assembly while being directly laminated on top of each other, the second electrode cores protruding from another end of the flat electrode assembly while being directly laminated on top of each other; and a first current collecting plate arranged in a first electrode core collected area where the mutually directly laminated first electrode cores protrude, the first current collecting plate being resistive-welded on one plane parallel to a plane on which the first electrode cores are laminated. A first electrode core melt-attached portion where the mutually directly laminated first electrode cores are melt-attached is formed in an area distanced from the area in which the first current collecting plate is attached.

摘要： In a prismatic sealed secondary battery according to an embodiment of the present invention, at least one of positive electrode substrate exposed portions and negative electrode substrate exposed portions of an electrode assembly is split into two groups, and therebetween are disposed intermediate members that are made of a resin material and hold one or more connecting conductive members. The two split substrate exposed portions are electrically connected to collector members and to at least one of the connecting conductive members by resistance-welding. Voids are formed in resin material portions of the intermediate members that are located around the resistance-welded portions of the connecting conductive members. Therefore, lowered resistance between the substrate exposed portions and the collector members and stabilized quality of the welds are realized and the manufacturing yield of the prismatic sealed secondary battery is improved.
