The reaction of the lithium with the oxygen of the process atmosphere led to the formation of lithium oxide, which settles in the form of a white powder on the surface of the cutting device. The metal fire was extinguished by suffocation using a steel plate. Without this intervention, the entire sample would have burned.
Apart from the current low stability of all solid-state separators, challenges lie in the general processing, as well as the handling and separation, of lithium metal foils. Unfortunately, lithium metal anodes cannot be separated by conventional die cutting processes in large quantities.
Author to whom correspondence should be addressed. Laser cutting is a promising technology for the singulation of conventional and advanced electrodes for lithium-ion batteries.
The aging causes an ongoing reaction of the lithium stability of the cutting edge depending on the process parameters and geometric shape. 3. Results on the physical and chemical properties of the cutting edge are considered sep arately. At first, the a constant dew point of −30 °C are presented.
Investigations on the influence of the cutting speed on the characteristics of the cutting edge during the laser cutting of lithium metal foils at a dew point of −30 °C show that the melting width decreases with the increasing cutting speed.
Unfortunately, lithium metal anodes cannot be separated by conventional die cutting processes in large quantities. Due to its adhesive properties and toughness, mechanical cutting tools require intensive cleaning after each cut.
