  "textContent": "The present application provides a battery and a portable electrical device. The battery of the present application includes a housing and a battery cell disposed in the housing; the battery cell includes electrodes (20) and tabs (30), and each of the electrodes (20) is integrally connected with a tab (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 the tab (30) is welded to the empty foil zone by a laser welding process; a surface of the empty foil zone facing away from the tab (30) has a plurality of welding zones (21) which are arranged at intervals, and each welding zone (21) comprises at least one line-shaped welding mark (211) and a surface of the tab (30) facing away from the empty foil zone has no welding mark. The protrusion of present application formed after the electrode (20) and the tab (30) of the battery are welded is less likely to pierce a separator between a positive electrode (20) and a negative electrode (20), and thus a short circuit could be prevented, which is beneficial to the improvement of the quality and safety performance of the battery.",
