Patent ID: 7910243

Claim:
A polymer battery pack comprising: a pouch type bare cell having an exposed electrode tab; a circuit electrically coupled to the electrode tab of the pouch type bare cell; a frame case covering an upper part of the pouch type bare cell where the circuit is arranged, the pouch type bare cell including two short side parts connected to the upper part of the pouch type bare cell and a lower part of the pouch type bare cell, and including two long side parts of a broader width than the two short side parts and connected to an exposed upper part of the pouch type bare cell; and a reinforcement label having a metal layer, the label being attached as a single body to the two long side parts and the lower part of the pouch type bare cell, wherein the frame case comprises a plane part that covers the upper part, the two short side parts and the lower part of the pouch type bare cell and wherein the frame case further comprises an extension part bent from an end of the plane part, and extended toward a corner of the two long side parts of the pouch type bare cell to cover the corner part of the two long side parts of the pouch type bare cell, and wherein the plane part of the frame case covering the upper part of the pouch type bare cell is wider than the plane part of the frame case covering the two short side parts of the pouch type bare cell, and wherein the plane part of the frame case covering the upper part of the pouch type bare cell is contiguous with and a continuation of the plane part of the frame case covering the two short side parts of the pouch type bare cell.
