    • A method for producing a prismatic secondary cell housing a flat electrode assembly includes disposing a first current-collecting member onto a first to-be-welded portion at a flat portion of an edge of the electrode assembly where a core-body exposed portion of the first electrode protrudes. A first receiving member is disposed onto a plane opposing the flat portion. The first current-collecting member, the core-body exposed portion, and the first receiving member are resistive-welded with the core-body exposed portion between the other members. A second current-collecting member is disposed onto a second to-be-welded portion at a position of the flat portion distanced from the first to-be-welded portion while avoiding contact between the collecting members. A conductive connecting member is placed between the collecting members or between the receiving members. The conductive connecting member and its abutting members are welded. One of the members is electrificably connected to an external output terminal.

    • A nonaqueous secondary battery 10 of the invention has an active material compound layer 14 deposed over at least one face of a collector 12 made of metal foil and is equipped with a positive electrode 11 having a portion 13 in a part of which metal is exposed. The positive electrode 11 together with the exposed-metal portion 13 faces a negative electrode 17 through an interposed separator 23, and on that part of the exposed-metal portion 13 that faces the negative electrode 17 through the interposed separator 23 there is formed a protective layer 16 made of a material whose electronic conductivity is lower than that of the metal and which moreover is non-insulative. With such nonaqueous secondary battery 10, should part of an electrode pierce the separator and contact with the other electrode, the battery will be gently discharged, thereby averting abnormal heat generation by the battery and additionally enabling the battery's abnormality to be sensed by the equipment via the fall in battery voltage. Thus, there is provided a nonaqueous secondary battery of excellent safety that can prevent abnormal heat generation due to a short circuit caused by burr, powder or the like piercing the separator.
    • 本发明的非水系二次电池10具有在由金属箔制成的集电体12的至少一个面上形成的活性物质化合物层14,并且配备有在其一部分露出金属的部分13的正极11。 正极11与暴露金属部13一起通过插入的隔板23面对负极17,并且通过插入的隔板23与露出金属部13的面对负极17的那部分形成保护 层16由电子导电率低于金属的材料制成,而且是非绝缘的。 对于这样的非水系二次电池10,电极的一部分应该与隔板接触并与另一个电极接触,电池将被轻轻地排出,从而避免电池发生异常的发热,并且还能够使电池的异常被设备通过 电池电压下降。 因此,提供了一种极好的安全性的非水二次电池,其可以防止由于由穿孔分离器的毛刺,粉末等导致的短路引起的异常发热。

    • This invention aims to provide a prismatic sealed secondary battery which is capable of ensuring a high battery capacity and suppressing the case swelling and which achieves high quality in appearance at low cost, and the method for manufacturing the same. To achieve the above objectives, the prismatic sealed secondary battery of the present invention has a structure in which an open end of the case that houses an electrode assembly therein is sealed by a sealing cap. On the main plane of the case, linear heat strain signatures are created. Additionally, depressions are formed along the heat strain signatures that are a principal cause of the depressions. On the case, within an area where the heat strain signatures have been created, a portion composed of a recrystallized structure is formed. This portion is, on cross section, fanned out inwardly the case plate from the center of linewidth of each heat strain signature.
