  • LASER WELDING METHOD AND MONITORING METHOD FOR SECONDARY BATTERY
    Publication number: 20240123548
    Abstract: Embodiments relate to laser welding methods, monitoring methods, and monitoring systems for a secondary battery. A laser welding method for a secondary battery includes performing laser welding on a positive electrode base having a thin-film shape in which a plurality of positive electrode base tabs are formed at a side, a negative electrode base having a thin-film shape in which a plurality of negative electrode base tabs are formed at a side, and a thin-film multi-tab to be joined to each of the positive electrode base and the negative electrode base, a welded portion in which the multi-tab is welded with the positive electrode base and the negative electrode base being melting-joined by using a laser such that a plurality of welding spots is formed on the welded portion.

  • Laser welding method and laser welding device for secondary battery
    Patent number: 11806807
    Abstract: Disclosed is a laser welding method for a secondary battery, in which a first electrode substrate tab and a second electrode substrate tab are laser-welded onto a first electrode uncoated region of a first electrode plate and a second electrode uncoated region of a second electrode plate, respectively, wherein the first electrode substrate tab and the second electrode substrate tab are fusion-bonded with a laser beam so as to have a preset welding pattern at welding portions thereof.
