MULTI-LAYER TABS WELDING METHOD FOR BATTERY AND BATTERY

Disclosed are a multi-layer tabs welding method for a battery and a battery. The method comprises conducting continuous scanning welding with laser on multi-layer tabs and a to-be-welded workpiece to form a strip-like or block-like welding bead, and repeating the aforementioned process to form a plurality of discontinuous welding beads at a connection between the multi-layer tabs and the to-be-welded workpiece.
