| 20110076531 | VOLTAGE SENSING MEMBER AND BATTERY MODULE EMPLOYED WITH THE SAME - Disclosed herein is a battery module configured in a structure in which two or more battery cells, each of which has electrode terminals formed at one end or opposite ends thereof, are stacked in a state in which the battery cells are electrically connected to each other, wherein the electrode terminals of the battery cells are formed of plate-shaped conductive members, the electrode terminals of the battery cells are folded such that the electrode terminals are in tight contact with each other to form a bent connection part at an electrical connection region between the battery cells, and the bent connection part is surrounded by a voltage sensing member mounted to the bent connection part. | 03-31-2011 |
| 20110076527 | DUAL SEALING CAP ASSEMBLY AND CYLINDRICAL SECONDARY BATTERY INCLUDING THE SAME - The present invention relates to a cap assembly and a battery including the same. More particularly, the present invention relates to a cap assembly for a cylindrical secondary battery, in which the support unit of a current interrupt device (CID) is seated in the inclined portion or the terraced portion of a gasket and thus the battery is dually sealed, thereby preventing the leakage of an electrolyte, and a cylindrical secondary battery including the cylindrical secondary battery. The cap assembly of the present invention is dually sealed for the leakage of an electrolyte. Accordingly, there is an advantage in that the safety of the battery can be greatly improved because the electrolyte is rarely leaked although the battery is shocked because of dropping. | 03-31-2011 |
| 20110070501 | ADDITIVE FOR ELECTROCHEMICAL ELEMENT TO IMPROVE SAFETY - Disclosed herein is an additive for improvement in safety of an electrochemical device, including an inner core and an outer coating layer, wherein the inner core is formed using a volume-expandable material fused at more than a predetermined temperature while the outer coating layer is formed using a conductive material with higher conductivity than that of the inner core and covers an outer face of the inner core. | 03-24-2011 |
