Laser Structuring of Composite Electrodes for Next-Generation Lithium-Ion Batteries
Pfleging, Wilhelm
Abstract:
The merge of Laser 3D Battery Concept and thick film concept enables high-energy and high-power operations at the same time while suppressing cell degradation processes at pouch cell level. For this purpose the ultrafast laser structuring was applied to energy storage materials such as ultra-thick film nickel-enriched NMC cathodes and silicon/graphite-based anodes. Upscaling of laser technology and the transfer into pilot lines is currently under development.
