Changing the game

cylib is a start-up for holistic and innovative battery recycling, starting from discharging to recovery of all components of the lithium battery.

cylib was founded in Aachen in 2022 by Lilian Schwich, Paul Sabarny, and Dr. Gideon Schwich.

Our process

cylib's proprietary end-to-end process is characterized by the efficient, resource- and climate-friendly recovery of all valuable metals in an electric car battery from pack to cell level.

The process has been developed over the years at RWTH Aachen University within an experienced research team.

Our drive was to develop a process that, in addition to robustness, has sustainability as a central element. Thus the cylib process is accompanied by a reduction in CO2 emissions.

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.
