Recycling fails due to chemical mix

Knowledge of cathode chemistry is increasingly decisive for the efficiency of modern recycling processes. The previous practice of processing heterogeneous batteries together leads to com-plex material flows and decreasing metal yields. The study "Identification of waste lithium-ion battery cell chemistry for recycling" by Finnish scientists shows that new diagnostic methods such as incremental capacity analysis can enable non-destructive pre-sorting for the first time. The study was published in "Waste Management".
