Material and production optimization for lithium-ion batteries with ceramic solid-state electrolytes

The importance of battery cells is growing rapidly. Particularly in their role as a core component of automotive electromobility, batteries are constantly being optimized to improve characteristics such as range, durability, safety, and cost. In light of the fact that excess capacity is available, and because other countries have amassed extensive experience with producing current battery generations, this joint project focuses on building and expanding knowledge about the next generations, which will replace the conventional lithium-ion battery and thus set the stage for battery cell production in Germany.

The objective of OptiKeraLyt is to explore industrial production methods for battery cells with ceramic solid-state electrolytes. These solid-state batteries or systems—which represent the fourth generation of cell technology—make it possible to achieve significantly higher levels of energy density and safety compared to conventional lithium-ion batteries (LIB). LIMO will be helping to develop a laser system as well as production processes to be used for manufacturing this new battery type. For LIMO, this means using beam shaping technology to transform laser beams into lines that allow the production process to be individually adapted to new battery material systems. Another positive aspect of this line beam shaping is the fact that the laser beams can be scaled to achieve greater processing speed, thereby forming the basis for efficient industrial battery-cell production.
