    • 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.
    • 棱镜二次电池设置有负极/正极集电体(18),其设置在卷绕的负极/正极基板露出部分(15)和负极/正极集电体接收部件(19)中的任一个上,负极/正极集电体接收部件 被布置在另一个表面上。 负极/正极集电体中的至少一个具有凹部(30),该凹部(30)部分地形成在不面向负极/正极基板露出部分的一侧的表面上,以便比另一部分的厚度薄。 在该凹部进行电阻焊接,在负极/正极露出部和负极/正极集电体之间形成大的焊接熔核。

    • 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.

    • The positive electrode substrate exposed portions or the negative electrode substrate exposed portions, or both, of an electrode assembly is split into two groups, and therebetween is disposed an intermediate member made of a resin material and holding one or more connecting conductive members. Collector members for the substrate exposed portions split into two groups is electrically joined by a resistance welding method to the substrate exposed portions split into two groups, together with the connecting conductive member(s) of the intermediate member. The resin material portion of the intermediate member protrudes, in the extension direction of the substrate exposed portions split into two groups, beyond the ends of the substrate exposed portions split into two groups and the ends of the collector member to a prismatic outer can. This structure enables enhanced resistance between the substrate exposed portions and the collector member and curbs variation in the welding strength.
    • 电极组件的正极基板暴露部分或负电极基板暴露部分或两者被分成两组,并且在它们之间设置由树脂材料制成并保持一个或多个连接导电部件的中间部件。 通过电阻焊接方法将基板暴露部分分成两组的集电体部件与中间部件的连接导电部件一起被分成两组的基板暴露部分。 中间构件的树脂材料部分在基板暴露部分的分成两组的延伸方向上突出超过分成两组的基板暴露部分的端部和集电体构件的端部到棱柱形外罐。 这种结构使得能够增强基板暴露部分和集电体部件之间的电阻,并且限制焊接强度的变化。

    • A prismatic sealed secondary battery according to an embodiment of the present invention includes an electrode assembly having stacked or wound positive and negative electrode substrate exposed portions and a pair of collector members electrically joined to the respective electrode substrate exposed portions. At least one of the electrode substrate exposed portions is split into two groups, and therebetween is disposed an intermediate member made of resin material and holding a plurality of connective conducting members. The collector member for the substrate exposed portions split into two groups is disposed on at least one of the outermost faces of the substrate exposed portions, and is electrically joined by a resistance welding method to the substrate exposed portions, together with the connecting conductive members of the intermediate member. This configuration lowers resistance of the electrode substrate exposed portions and the collector members and curbs variation in the welding strength.
