Cylib

Cylib is a German battery recycling company founded in 2022 as a spinoff from RWTH Aachen University, headquartered in Aachen, Germany. It transforms end-of-life lithium-ion batteries, production scrap, and black mass back into critical raw materials, recovering lithium, graphite, nickel, cobalt, and manganese through a proprietary, largely water-based hydrometallurgical process that the company reports achieves over 90% recycling efficiency with an ~80% reduced carbon footprint versus primary extraction, powered by 100% renewable electricity. The company is backed by Speedinvest and other investors. Cylib operates as an industrial cleantech / circular-economy materials business and does not currently publish a developer program, public API, developer portal, SDKs, or other software integration surface; this profile was added to the API Evangelist network as a portfolio-lead stub and carries only identity and public web properties.

Cylib is profiled on the APIs.io network. Tagged areas include Company, Battery Recycling, Lithium-Ion, Circular Economy, and Cleantech.

Cylib’s developer surface includes engineering blog, support, and 4 more developer resources.
