Patent number: 8679673Abstract: Provided are a cap assembly and a can, and a secondary battery. The secondary battery includes a plurality of bare cells, each of which includes a cap-up used as an electrode terminal; and a conductive plate installed on top of the cap-ups and connecting a plurality of adjacent bare cells in series or in parallel, wherein a plurality of embossments are formed on the cap-up, a slit is formed in the conductive plate, and the conductive plate is welded to the embossments. Therefore, since a cap-up may be properly welded to a desired position on a conductive plate, bad welding may be reduced, and welding strength may be improved.Type: GrantFiled: August 2, 2010Date of Patent: March 25, 2014Assignee: Samsung SDI Co., Ltd.Inventor: Hun-Tae Ro

Patent number: 8673481Abstract: A housing (610, 620) for a button-type battery (?) includes a cavity with resilient conductive terminals (300, 400) therein and a door (500) opposite the terminals (300, 400). When a battery (?) is pushed inside the cavity and the door (500) is moved to its closed position, the resilient terminals (300, 400) hold the battery (?) in place, applying a force urging the battery (?) against the door (500) to better maintain electrical contact. When the door (500) is moved to its open position, the resilient terminals (300, 400) push the battery (?) at least one fifth of its diameter out of the cavity, so a user can pull out the battery (?) by hand and change the battery (?) easily.Type: GrantFiled: March 9, 2009Date of Patent: March 18, 2014Inventor: Gang Chen

Patent number: 8669004Abstract: According to an embodiment, a battery pack includes a battery cell, a circuit module, and a cover. The circuit module is coupled to the battery cell by lead plates. Terminals are disposed on a top surface of the circuit module. The cover is coupled to the circuit module and the battery cell and exposes the terminals to an exterior environment. At least one support plate is disposed between the circuit module and the battery cell. Thus, the support plate prevents the circuit module of the battery pack from being bent.Type: GrantFiled: May 27, 2010Date of Patent: March 11, 2014Assignee: Samsung SDI Co., Ltd.Inventor: Bongyoung Kim
