Battery cells use alternating layers of anode and cathode foils in electrode production. They are separated by separators. The foil stack is then rolled up, packed in a metal housing and the batteries will be finally welded.
PMT offers optical geometrical measurement solutions for flat foil inspection for quality purpose. parts control systems are used in numerous process steps to ensure efficient production of the battery cells. This includes, for example, measuring the electrode foil thickness, checking the cutting burr and laser welding the foil layers (foil-to-tab) and the housing with the lid (cap-to-can).
