The utility model provides a kind of non-
woven fabric composite
current collector tab
welding structure, belong to composite
current collector technical field, including tab, tab includes two
metal layers, and the insulating layer between two
metal layers, including plate, at least one
metal quality convex strip is equipped on one plane of plate;Plate is attached on one of metal layer, and convex strip can be penetrated two metal
layers and insulating layer, to make two metal layers can be realized
electrically conductive by penetrating convex strip;The end portion after the convex strip penetrates tab is welded and fixed with soft connecting sheet, to form the electric connection passage of tab and soft connecting sheet;The utility model can reduce the material usage amount of
metal foil, reduce the stacking number of tab
welding area while reducing manufacturing cost, and directly reduce the
welding frequency between material, significantly improve welding efficiency, while greatly reduce the risk of
soldering point drop, further improve the long-term stability of tab and soft connecting sheet connection.
