New paper: Spectral Characterization of Battery Components from Li-Ion Battery Recycling Processes

Excited to share a new paper on „Spectral Characterization of Battery Components from Li-Ion Battery Recycling Processes“ led by Julia Richter! The work was done in close collaboration between TU Bergakademie Freiberg and Helmholtz Institute Freiberg within the BMBF funded project DIGISORT. Addressing the critical need for efficient and cost-effective recycling strategies amidst the rising demand for Li-ion batteries, our study focuses on employing optical sensors for non-contact, real-time monitoring of battery component detection. Investigating mm-scale particles from end-of-life Li-ion batteries using five reflectance sensors, we identified the visible to near-infrared range (400–1000 nm) as optimal for discriminating between Aluminum (Al), Copper (Cu), and other vital battery components in the recycling material stream and provide practical recommendations for industry application.
