ReLIB project receives funding from "Innovationskorridor Berlin – Cottbus"
The „Innovationskorridor Berlin – Cottbus“ is a joint initiative of BTU Cottbus-Senftenberg and Humboldt Universität zu Berlin, to strengthen the cooperation between the two universities and regions. We are happy to announce that we have been awarded one of the four seed funds for our joined project ReLIB on the recycling of lithium-ion batteries. This will support our collaboration with the groups of Jörg Acker (BTU), Jan Ingo Flege (BTU), Olaf Klepel (BTU) and Arnd Garsuch (BTU/BASF). We would like to thank the BTU Cottbus-Senftenberg and Humboldt Universität zu Berlin for their support and all the other participants for the great day in Cottbus.
