Electromobility sets challenging requirements for new high-performance batteries – cruising range, life span, safety or charging times, to mention just a few. An intrinsic challenge is the resource requirement for a growing number of large car batteries. This is exactly where the project comes in.
The objective of the ECO COM'BAT was to combine resource-efficient and high-performance materials for the next generation of high-voltage lithium-ion batteries. One main focus was on the substitution of cobalt in the electrodes and of fluorine in the electrolyte. To this end, the production of specially selected electrode and electrolyte materials had to be scaled up from a technology readiness level (TRL) of 5 to 7. The new materials had to be adjusted to each other and to be qualified in prototype lithium-ion battery cells. With a view to a sustainable circular economy, it was also intended to consider efficient battery recycling.
EIT RawMaterials, initiated and funded by the EIT (European Institute of Innovation and Technology), a body of the European Union, is the largest consortium in the raw materials sector worldwide. Its vision is to develop raw materials into a major strength for Europe. Its mission is to enable sustainable competitiveness of the European minerals, metals and materials sector along the value chain by driving innovation, education and entrepreneurship.
