BATTERY, MANUFACTURING METHOD THEREOF AND ELECTRONIC PRODUCT

The present application provides a battery, a manufacturing method thereof and an electronic product, and the battery includes a housing and a battery cell accommodated in the housing. The battery cell includes electrodes (20) and tabs (30), where each of the electrodes (20) includes a current collector and an active material layer, and the current collector includes a coating zone coated with the active material layer and an empty foil zone not coated with the active material layer, and an end of a tab (30) overlaps the empty foil zone and the tab (30) and the empty foil zone are fixedly connected by laser welding; the side of the empty foil zone facing away from the tab (30) has a plurality of dot-shaped welding marks (21) arranged at intervals, and the dot-shaped welding marks (21) include a concave part (211) and an annular convex part (212) surrounding the periphery of the concave part (211). Furthermore, the surface of the tab (30) facing away from the empty foil zone has no welding mark. The contact area between the annular convex part (212) and the separator between the positive electrode (20) and the negative electrode (20) in the present application is relatively large, and the separator is less likely to be pierced, and thus a short circuit could be prevented, which is beneficial to the improvement of the quality and safety performance of the battery.
