Patent ID: 8252453

Claim:
A secondary battery, comprising: a bare cell including a first electrode terminal, and an outer peripheral surface acting as a second electrode terminal having a polarity opposite to the first electrode terminal and comprising a plurality of major surfaces separated by a plurality of minor surfaces; a protection circuit module installed on one of the plurality of minor surfaces of the bare cell; first and second lead plates both installed together on a same minor surface of the bare cell, the first and second lead plates respectively configured to electrically couple the protection circuit module to the first and second electrode terminals, the first and second lead plates both extending in a side-by-side relation in a same longitudinal direction of the same minor surface between the protection circuit module and the same minor surface of the bare cell, and the first and second lead plates being spaced apart from each other across the same minor surface; and a discrete outer cover attached exclusively on the minor surface of the bare cell where the first and second lead plates are installed, so as to cover the first and second lead plates, the outer cover exposing at least two contiguous minor surfaces of the bare cell.
