| titleOfInvention | Multi-pole-tab wound lithium-ion battery structure |
| abstract | The utility model relates to the technical field of lithium ion batteries, in particular to a multi-pole-tab wound lithium ion battery structure. It includes a plurality of winding cores connected in parallel. The winding core is formed by winding a negative electrode sheet and a positive electrode sheet. The top of the negative electrode sheet is evenly provided with a number of negative electrode current collector pole handles, and the top of the positive electrode sheet is evenly provided with a number of positive electrode current collector electrodes. The handle, the negative current collector handle and the positive current collector handle are arranged oppositely on both sides of the top of the winding core, an insulating sleeve is arranged between the negative current collector handle and the positive current collector handle, the top of the core is provided with a cover plate, and the negative collector is provided with an insulating sleeve. The fluid pole handle and the positive current collector pole handle are respectively connected to the bottom of the cover plate through a shunt piece. It has the same current-carrying area as the laminated battery structure, which can improve the high-rate charge and discharge performance and reduce the welding stress of the tabs. Compared with the use of multiple positive and negative pole pieces in the laminated structure, the probability of edge defects of the pole pieces is greatly reduced, and the risk of internal short circuit is reduced. |
