About us

cylib is a research-based German scaleup for holistic battery recycling - starting from discharging to recovery of all components of the lithium battery - that was founded in Aachen in 2022 by three visionary founders, including a female CEO.
Our process

The cylib process offers a complete end-to-end process from battery pack to green battery material by employing a combination of mechanical and thermal pre-treatments and an innovative water-based lithium and graphite recovery. Unlike incumbents, cylib can therefore recover battery materials such as lithium, graphite or manganese. The process was developed over several years of research at the renown RWTH Aachen University and offers an efficient, resource- and climate friendly recovery of all battery materials from end-of-life batteries.

cylib's technology enables the recovery of all battery components regardless of whether it is an end-of-life battery or not. Recovery of green secondary raw materials from the cylib process enables the realization of the true Circular Economy on the European market.
