| 20130040192 | POUCH TYPE LITHIUM SECONDARY BATTERY - A pouch type lithium secondary battery includes: an electrode assembly including electrode tabs respectively connected to two electrodes, the two electrodes having different polarities; and a case to house the electrode assembly such that the electrode tabs extend to the outside of the case, wherein one stepped part through which the two electrode tabs simultaneously extend is formed in a sealing portion of the case. In the electrode sealing portion of the pouch type lithium secondary battery having short width, sealing of the case is improved by the one stepped part, thereby improving efficiency of the manufacturing process of the battery. | 02-14-2013 |
| 20120135307 | NEGATIVE ACTIVE MATERIAL FOR RECHARGEABLE LITHIUM BATTERY, METHOD OF PRODUCING NEGATIVE ELECTRODE AND RECHARGEABLE LITHIUM BATTERY INCLUDING SAME - Disclosed are a negative active material of a rechargeable lithium battery and a rechargeable lithium battery including a negative electrode, and the negative electrode includes a negative active material layer including a negative active material represented by the following Chemical Formula 1. | 05-31-2012 |
| 20120070737 | BINDER COMPOSITION FOR RECHARGEABLE LITHIUM BATTERY, AND ELECTRODE AND RECHARGEABLE LITHIUM BATTERY INCLUDING THE SAME - Disclosed are a binder composition for a rechargeable lithium battery including a cross-linked compound of polyacrylic acid substituted with an alkali cation and polyvinyl alcohol and an electrode and rechargeable lithium battery including the same. The cross-linked compound of polyacrylic acid and polyvinyl alcohol is obtained by heating polyacrylic acid and polyvinyl alcohol to effect a cross-linking reaction via esterification. The cross-linked compound of polyvinyl alcohol and polyacrylic acid substituted with an alkali cation may improve phase stability of a binder, and has high cross-linking ratio, thereby providing for excellent performance of a rechargeable lithium battery. | 03-22-2012 |
