| 20110165444 | SORT OF LI-ION POWER CELL - A Li-ion power cell includes at least two winding cores produced by a winding process. Each of the winding cores has an anode tab and a cathode tab. The anode tabs and the cathode tabs of the respective winding cores are connected in parallel, respectively. The winding core is of cylindrical or diamond shape. The Li-ion power cell further includes a housing, an anode pole and a cathode pole which are disposed on the housing. The anode tabs of the respective winding cores are connected in parallel and then electrically connected to the anode pole, and the cathode tabs of the respective winding cores are connected in parallel and then electrically connected to the cathode pole. | 07-07-2011 |
