Latest Patents

Thümmler is named on 1 patent: “Method and Device for Cutting a Metal-Containing Foil, and Laser-Cut Metal-Containing Foil.” The invention uses controlled pulsed laser radiation to cut through at least one metal layer, aiming to sublimate most of the metal rather than melt it. This process helps limit bead structures and splashes of solidified metal along the cut edges. In battery applications, cleaner edges may support improved electrical performance and durability while reducing the risk of short circuits.
