METHOD FOR WELDING ELECTRODE TAB OF SECONDARY BATTERY AND ELECTRODE ASSEMBLY MANUFACTURED USING SAME |
摘要 |
Disclosed herein are a method for welding electrode taps of a secondary battery which improves insulation defects generated during welding between the electrode taps and lead parts and an electrode assembly manufactured thereby. The method for welding electrode taps includes performing main welding to connect electrode taps protruded from electrode plates provided in a battery and lead parts electrically connecting the electrode taps to external terminals and having a lead film on the surfaces thereof and, in main welding, a welding part is formed in a partial section of an overlapping region between the electrode tap and the lead part, and a non-welding section is formed between the welding part and the lead film. |
