New Energy Lithium Battery Die Cutting

How to cut lithium ion battery electrodes?

Currently, the predominant techniques employed in lithium-ion battery (LIB) manufacturing facilities for electrode cutting involve the utilization of knife molds and hardware die punching.

Why is laser cutting electrode a good choice for lithium ion batteries?

Furthermore, the excellent structural uniformity reduces the generation of electrode lithium dendrites and ensures the battery's safety. On the other hand, the enhancement of LIBs performance with the laser cutting electrode can also be attributed to the interaction between the laser and the electrode material.

Can lithium metal anodes be separated by die cutting?

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.

Can lithium metal foils be separated by a die cutting process?

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.

Can remote laser cutting be used in a lithium ion battery production line?

However, remote laser cutting is not state of the art in a conventional lithium ion battery production line, even though it is a highly reproducible, wear-free and flexible cutting method.

What happens if a lithium cutting device is suffocated?

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.
