No Canary’s R&D lines for Battery Recycling are designed as pilot plants for research and development in the field of lithium-ion battery recycling. These compact recycling plants enable research institutions, universities, and corporate R&D departments to test sustainable recycling processes on a small scale and then successfully transfer them to industrial scale. With their modular design and realistic representation of all important process steps, the R&D Lines form an important bridge between the laboratory and industrial application – they create a protected space in which new processes can be developed and optimized under practical conditions before being used in large-scale plants.

All central process steps of battery recycling are represented in the technical core of the R&D pilot plant. The deactivated lithium-ion batteries are first shredded in a vacuum chamber at a pressure of up to 5 mbar. This vacuum shredding not only ensures safe, controlled shredding without the risk of explosion, but also facilitates the subsequent steps, as the extreme vacuum already removes a large proportion of the volatile ingredients. Immediately after the shredder, the shredded material undergoes an intensive drying process that extracts any remaining moisture and electrolyte from the battery residues. The organic solvents in the electrolyte that evaporate during this process – i.e., the VOCs (volatile organic compounds) – are collected and condensed in a special condensation system. In this way, the plant recovers the volatile electrolyte components instead of allowing them to escape uncontrolled into the environment. This combination of vacuum comminution, intensive drying, and VOC condensation ensures that the end result is dry, largely degassed comminuted material (black mass and other fractions) that is optimally suited for further processing.
