Laser Cutting converts coated Lithium foil into Discrete Parts
Solid-State Batteries are regarded as a large contributor in the Energy Transition and a next push for the EV growth roadmap. More energy density in a smaller package, produced with various technologies and different materials, will make that happen. Various suppliers use innovative technologies and new production methods to make their solid state battery.
Nearly all of the innovative solid state battery concepts are based on small discrete sheets of a metal foil, mostly Lithium, with a layer of sensitive (ceramic) active material. To cut the discrete sheets from a roll is a deliquiate process. Laser cutting is very well capable for cutting these discrete parts from a roll, as it enables and guarantees:
- A constant quality (no wearing of tools)
- A high edge quality without mechanical damage, bending or stress
- Identification of each sheet with traceable inspection data
Zenna is a Dutch specialist in building laser converting machines for clients with challenging requirements. To cut sensitive cathode foil into discrete sheets for solid-state batteries, the FlexCutter R2DP was developed. This innovative laser system uses ultra high frequency lasers and includes a specially designed material transport, a cleanroom housing and dedicated inspection steps to record and safeguard the quality of the cut products.
The major reasons to consider laser cutting systems from Zenna are:
Flexibility
- Any laser type: fiber high frequency co2 laser
- Any hole size & pattern – multi-hole, 1mm ~ 10mm holes, slits and fingers
- Positioning with scanner as well cartesian system
Innovative
- As module in an existing line or as complete system
- Special shapes, multi-holes, waves, sharp edges
Experience
- Over 30 years of engineering and building experience
- Worldwide installation and service
Quality
- First disc has the same quality cut as Last disc of a job, no wear
- Sharp edges, no threats, no burning marks (except phenol-based resin )
