Structural mechanical cathode adaptation to silicon and lithium based anode materials (KaSiLi)
The EBZ Dresden research consortium is developing key components for a new battery generation including a significant increase in energy density compared to today's lithium ion cells within the KaSiLi project (Structure Mechanical Cathode Adaptation for Silicon and Lithium Materials).
Thin lithium or silicon layers form the anodes of these battery cells and their high specific capacity enables a leap in energy density of up to 70 %. The project’s success depends on a fundamental understanding of the electrochemical and structural material properties, new methods for the production of electrode materials, and a holistic approach involving cathode and cell design.
Thanks to their lower weight and volume, the new battery generations can, in future, significantly increase the range of electric vehicles and enable new applications (e.g. in electric aviation).
