For laser cutting of electrodes a high degree of process readiness level is achieved, and commercial ns-laser cutter systems adapted to battery manufacturing are available and can be introduced in cell manufacturing. Nevertheless, laser cutting will be further developed regarding next generation of batteries using the thick-film concept.
The quality of the electrode cutting edge during the electrode cutting process has a significant impact on battery performance and quality. Laser cutting, by optimizing cutting parameters, can reduce issues such as coating detachment, exposure of metal foil, and debris, thereby enhancing battery performance and safety.
Lithium Electrode Die Cutting Process Principle: Die cutting is a process that uses steel molds to cut the positive and negative electrode materials of lithium batteries. The shape and size of the mold are the same as those of the positive and negative electrodes of the lithium battery.
III. Principle of Electrode Laser Cutting The basic principle of laser cutting is to use a high-power density laser beam to irradiate the battery electrodes to be cut, heating the electrodes rapidly to a high temperature, causing them to melt, vaporize, ablate, or reach the ignition point to form holes.
This paper investigates 19 Li-ion cylindrical battery cells from four cell manufacturers in four formats (18650, 20700, 21700, and 4680). We aim to systematically capture the design features, such as tab design and quality parameters, such as manufacturing tolerances and generically describe cylindrical cells.
Principle: Slitting is a process that uses rotating blades or laser beams to cut the positive and negative electrode materials of lithium batteries.
