Title:
BATTERY ELECTRODE SHEET AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/066655
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of batteries, and particularly to a battery electrode sheet. The battery electrode sheet comprises an electrode sheet body and a tab. The electrode sheet body comprises a current collector and a coating that coats a surface of the current collector, and a surface of the electrode sheet body has a slot region and a thinned region, wherein the current collector is exposed to a surface of the slot region of the electrode sheet body and is welded to an end of the tab, and the coating is exposed to a surface of the thinned region of the electrode sheet body and is close to the tab. By means of optimizing the structure of the electrode sheet, the present invention can simplify the production process, avoid battery safety problems, and facilitate the improvement in the quality of a battery. In addition, further disclosed in the present invention is a preparation method for a battery electrode sheet.
