| 20090305120 | SYSTEMS AND METHODS FOR RECHARGEABLE BATTERY COLLECTOR TAB CONFIGURATIONS AND FOIL THICKNESS - Systems and methods for configuring tabs on a rechargeable battery may include a current collector comprising one or more collector foil and one or more tabs connected to the collector foil for conveying generated current from the current collector. The tabs may be configured to extract greater capacity from the battery electrodes so that the resulting battery may exhibit higher performance. The tabs may be configured so that the length of the tab is greater than the height of the collector foil so the tab may cover the height of the collector foil and may protrude from the foil. | 12-10-2009 |
