20110052939 | SECONDARY BATTERY - A secondary battery, including a cylindrical bare cell including a cylindrical can and a cap assembly coupled with the cylindrical can, wherein the cap assembly forms a first electrode and the cylindrical can forms a second electrode; a protective circuit module (PCM) separated from the cap assembly, connected to the cap assembly by a first connecting tab, and connected to the cylindrical can by a second connecting tab; a first external terminal provided on a top of the PCM; and a second external terminal electrically connected to the PCM and provided on a bottom surface of the cylindrical can. | 03-03-2011 |
20110059338 | Battery Pack - A battery pack having increased resistance against an external impact by increasing a coupling strength between a bare cell and a case resulting in increased reliability and quality. The battery pack includes a bare cell; a circuit module electrically connected to the bare cell; a frame case surrounding the bare cell and including a channel groove arranged at a region facing the bare cell; and a coupling reinforcement portion arranged in the channel groove to couple the frame case to the bare cell. | 03-10-2011 |
20110076520 | Secondary battery - Disclosed is a secondary battery that includes a bare cell, a first circuit module, and a second circuit module. The bare cell includes an electrode terminal connected to one type of polarity of the battery and a plate terminal connected to another type of polarity of the battery. The first and second circuit modules are disposed on an upper surface of the plate terminal, and are disposed at opposite sides of the electrode terminal. External terminals, which are mounted on the second circuit module and are electrically coupled to an external device, are positioned higher than the electrode terminal. This structure of the battery minimizes the size of the battery. | 03-31-2011 |
