Abstract:
A method of forming edge materials on an electrochemical cell component having a metallic foil substrate including a conductive coating on top and bottom surfaces and first and second edge portions extending laterally outward beyond the conductive coating, includes pulling the metallic foil substrate from a roll, feeding the metallic foil substrate through a profile machine and forming notches within the first and second edge portions that extend inwardly from outermost edges of the first and second edge portions a distance less than a distance between the outermost edges and the conductive coating, and define a plurality of electrode tabs, feeding the strip of metallic foil substrate sequentially through a plurality of 3-dimensional printing machines and printing edge materials onto the electrode tabs and the first and second edge portions between the plurality of electrode tabs, and rolling the strip of metallic foil substrate onto a roll.
