Laser Welding Apparatus for Secondary Battery

Abstract

Proposed is a laser welding apparatus for a secondary battery including a lower clamp configured to support a joint area of a plurality of electrode tabs extending from an electrode assembly and an electrode lead stacked on the plurality of electrode tabs, an upper clamp configured to press the joint area of the plurality of electrode tabs and the electrode lead and to have a through hole therein, and a laser generator configured to emit a laser beam, wherein the laser beam passes through the through hole to weld the plurality of electrode tabs and the electrode lead to enable electrical connection.

Dependencies are inferred from the claim text.
