All-solid-state approaches promise highest energy densities for lithium-ion batteries. On the cathode side, intensive research is being carried out, whereas on the anode side, the use of pure lithium metal is predominantly referred to. However, handling and processing of lithium metal is problematic, since lithium is a highly reactive alkali metal. Laser cutting has already proven to be a flexible and wearless process for the use of the electrode assembly for the production of lithium-ion batteries. Due to this highly reproducible assembly, laser cutting represents a qualitatively robust method for separating lithium metal.
