METHOD FOR WELDING METAL TAB OF ELECTRODE LAYER FOR CABLE BATTERY AND ELECTRODE MANUFACTURED THEREBY |
摘要 |
Disclosed are a method of welding a metal tab of an electrode layer for a cable battery and an electrode manufactured thereby. This welding method, suitable for welding a metal tab to an electrode including a current collector for a cable battery, a conductive layer formed on the outer surface of the current collector, and a polymer film layer formed on the inner surface of the current collector, includes: a) removing a portion of the conductive layer using a pulse laser, thus exposing the surface of the current collector positioned thereunder, and b) welding a metal tab to the surface of the current collector, thus enabling the welding of a metal tab and an electrode for a cable battery, which has been difficult to achieve using a conventional welding process. |
