2.2. Laser cutting in lithium ion battery production Remote Laser cutting of conventional lithium-ion battery foil (NMC, NCA, LFP cathodes or graphite anodes) is a method widely discussed in the scientific landscape for separation of electrodes [Lee et al., 2013],[Luetke et al., 2011 // 2014],[Reincke et al., 2015].
Summary and Future Work The presented work discussed experiments of laser cutting of electrode materials for the production of lithium ion cells. The experiments focused on the cutting edge quality. The cutting edge quality was investigated by evaluating the geometrical parameters in macroscopic cross sections.
The lithium sheets were placed on a flat sanded steel plate in focus level of the laser. In the cutting area the steel plate is grooved to avoid a reaction with respectively welding on the steel plate. For the cutting experiments lithium metal foils (Rockwood Lithium) with a thickness of 50 μm were applied.
Modern laser technology using beam deflection units is again proving to be the best solution for efficient production, especially for cutting foil rolls in battery production. There are currently three cell formats used in the production of lithium-ion batteries: pouch, cylindrical and prismatic cells.
The reason being that faster and more precise manufacturing leads to enormous cost savings in production. Modern laser technology using beam deflection units is again proving to be the best solution for efficient production, especially for cutting foil rolls in battery production.
Different research groups are investigating the influence of several production processes on the quality of the produced lithium ion battery cell. One investigated process is the cutting of the cell electrodes.
