Patent ID: 8394528

Claim:
A lithium polymer battery, comprising: a chargeable and dischargeable bare cell comprising an electrode assembly and an exterior case, the exterior case comprising a metallic layer interposed between two insulating layers, the metallic layer being exposed along an edge of the exterior case; a protective circuit cover comprising an inner surface and an outer surface, the protective circuit cover installed on one side of the bare cell and coupled to the bare cell, the protective circuit cover comprising an electrically conductive terminal on the inner surface facing the metallic layer exposed along the edge of the exterior case; and a holder cap comprising an inner cap, an outer cap, and a body connecting the inner cap and the outer cap such that the inner cap opposes the outer cap with a gap therebetween, wherein part of the protective circuit cover is inserted between the inner cap and the outer cap, and wherein the inner cap covers at least part of the electrically conductive terminal and contacts the metallic layer, and wherein the electrically conductive terminal would contact the metallic layer exposed along the edge of the exterior case but for the holder cap, wherein a resin molding part seals both the protective circuit cover and the holder cap, and wherein a locking ridge is formed on an end part of at least one of the inner cap and the outer cap of the holder cap.
