Sustainable technology for Li-ion battery recycling, for a true circular economy.

cylib aims to secure global raw material demands by recycling Li-ion batteries. This is realized by a proprietary, resource-efficient and environmentally friendly end-to-end process. The holistic cylib-process gives commodities another life by treating used batteries and transforming them into marketable raw materials. With cylib’s process, it is possible to recover all battery components. This also includes Lithium and Graphite among other materials that are currently not recovered from batteries in the EU.

‍

The recycling process was developed over many years of research at RWTH Aachen University and contains all the relevant process steps, like mechanical, thermal and chemical treatments to reach high yields.
