    • Provided is a secondary battery of an assemble-type structure, comprising: a cell body including an electrode assembly of cathode/separator/anode sealed therein; and a cap assembly including a protection circuit electrically connected to the cell body so as to control overcharge, overdischarge and overcurrent of the battery and a cap housing covering an upper part of the battery, and being detachably coupled to the cell body. In accordance with the present invention, since the cap assembly including the protection circuit, cap housing and the like is assembled detachably from the cell body and electrically connected to and also can be physically firmly fixed to one another, provided are effects capable of greatly reducing the manufacturing process steps of the battery, and solving all the problems associated with use of battery cases and insert injection molding. Therefore, the present invention can reduce battery production costs and rejection rate, facilitate greater ease of re-working upon occurrence of rejection in particular components and realize more efficient automation of the battery manufacturing process.
    • 本发明提供一种组装式结构的二次电池,其特征在于,包括:密封于其中的阴极/隔板/阳极电极组件的电池体; 以及盖组件,其包括电连接到电池体的保护电路,以便控制电池的过充电,过放电和过电流以及覆盖电池的上部的盖壳体,并且可拆卸地联接到电池体。 根据本发明,由于包括保护电路,盖壳体等的盖组件可从电池体拆卸地组装并且电连接到并且也可以物理上牢固地固定在一起,只要能够大大减少的效果 电池的制造工艺步骤,并解决与使用电池盒和插入注塑相关的所有问题。 因此,本发明可以降低电池生产成本和废弃率,便于在特定部件的排斥发生时更容易重新工作,并实现电池制造过程的更有效的自动化。
