| 发明名称 | Multiple conductive tabs for facilitating current flow in batteries | ||
| 摘要 | The disclosed embodiments provide a battery cell. The battery cell includes a set of layers which are wound together to form a jelly roll, including a cathode with an active coating, a separator, and an anode with an active coating. The battery cell also includes a pouch enclosing the layers, wherein the pouch is flexible. To increase a current flow in the battery cell, a first set of conductive tabs is coupled to a cathode substrate of the cathode, and a second set of conductive tabs is coupled to an anode substrate of the anode. | ||
