Title:
BATTERY AND ULTRASONIC WELDING SYSTEM USED IN MANUFACTURE OF SAID BATTERY
Document Type and Number:
WIPO Patent Application WO/2011/118565
Kind Code:
A1
Abstract:
In the disclosed tab bundle and lead welding, bad connections between electrode terminals and tab-damaged electrode plates are avoided by putting the electrode-side edges of a lead in an up-lifted state without joining the electrode-side lead edges to a tab bundle that extends from an electrode layer body, notwithstanding that the ends of the lead are joined. The disclosed battery is equipped with: an electrode layer body (10) that consists of multiple, layered electrode plates; and a lead (17), one end of which is joined to a tab bundle (15) that extends from each of multiple electrode plates. The lead end (17) and the tab bundle (15) include at least the edge (17a) of the lead (17) and are joined by ultrasonic welding.
