Tab welding structure and storage battery assembly

The utility model discloses a tab welding structure and a storage battery assembly. The tab welding structure comprises a busbar provided with a welding surface; the plurality of tabs are distributed in an array; the edge of the upper end of the tab is a bent part, and the bent part is welded to the welding surface of the busbar. The storage battery assembly comprises the tab welding structures, and also comprises positive plates with the same number as the tabs of one group of tab welding structures and negative plates with the same number as the tabs of the other group of tab welding structures, and the plurality of positive plates and the plurality of negative plates are arranged and distributed in a staggered manner. According to the utility model, by changing the tab structure, the resistance of electric connection is reduced, the discharge performance is effectively improved, and the start-stop performance of the EFB battery is effectively improved; moreover, in the production process, the original prod
