Laser Micro Tech: Sheet Cutting Machine LMTS IR Duo For Particle Reduced Laser Cutting

The Battery Show exhibitors Laser Mikrotechnologie walk us through the their technique for the cutting of coated Anodes and Cathodes for Pouch and Hardcase Cells.

Their technique was as follows:

  • Avoidance of particles which are caused by the conventional Laser cutting process
  • Particles can penetrate the separator and lead to a micro short circuit
  • Separator perforation and micro short circuits are causes of the critical exothermic reaction of a lithium cell
  • The exothermic reaction can lead to burning of the cell and subsequently burn the entire battery
