    摘要： In a secondary cell comprising an electrode unit enclosed in a cell can and adapted to deliver electric power generated by the electrode unit via electrode terminal assemblies, each electrode terminal assembly comprises an electrode terminal member extending through a center hole in a lid of the can, an insulating seal member provided in the center hole of the lid around a screw shank of the electrode terminal member, and a nut screwed on the screw shank of the electrode terminal member projecting outward from can. The insulating seal member is in engagement with the can and the flange of the electrode terminal member and nonrotatable relative to the cell can and the flange, whereby the electrode terminal member is prevented from rotating with the nut when the electrode terminal assembly is fixed to the lid.

    摘要： A prismatic secondary battery is provided with a negative/positive electrode collector (18), which are disposed on either one of a wound negative/positive electrode substrate exposed portion (15), and a negative/positive electrode collector receiving member (19) which is disposed on another surface. At least one of the negative/positive electrode collector has a recess portion (30) formed in part on a surface on the side not facing the negative/positive electrode substrate exposed portions so as to be thinner than the thickness of the other portion. Resistance welding is carried out in this recessed part, thereby a large welding nugget is formed between the negative/positive electrode exposed portion and the negative/positive electrode collector.

    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.
