WELDING METHOD FOR ELECTRODE TAB OF SECONDARY BATTERY AND ELECTRODE TAB WELDING STRUCTURE PRODUCED BY THE SAME

摘要

Disclosed is a method of welding an electrode tab of a secondary battery, including steps of: manufacturing an electrode assembly having a positive electrode plate, a separator, and a negative electrode plate; aligning at least two electrode tabs extending at the predetermined length from one side of the electrode assembly; and performing welding in the longitudinal direction of the electrode tab in an area where the electrode tabs are overlapped.
