Zusammenfassung: | The utility model relates to the technical field of lithium batteries, and particularly relates to a battery positive electrode plate with a novel structure. The battery positive electrode plate of the novel structure comprises a dressing region coated by a positive electrode material, and the dressing region is provided with an empty foil part; a tab is welded on the empty foil part, and the tab is provided with a protective adhesive tape of an insulator in a pasted mode at one side or two sides of a butt-joint point; after a battery coil core is formed, the empty foil part at one side or two sides of the butt-joint point is provided with the protective adhesive tape of the insulator so as to protect two side edges of the tab, and the situation of pole plate cutoff caused by the cutoff of the empty foil part and the dressing region cannot happen; the fault of the battery cell and other safety hazard which are caused by battery cell fragments are prevented. |
