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. |
