Sustainable upcycling of mixed spent cathodes to a high-voltage polyanionic cathode material

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: May 14, 2024

Abstract Sustainable battery recycling is essential for achieving resource conservation and alleviating environmental issues. Many open/closed-loop strategies critical metal or direct recovery aim at a single component, the reuse of mixed cathode materials significant challenge. To address this barrier, here we propose an upcycling strategy spent LiFePO 4 Mn-rich cathodes by structural design transition replacement, which uses green deep eutectic solvent to regenerate high-voltage polyanionic material. This process ensures complete all elements in can be reused. The regenerated LiFe 0.5 Mn PO has increased mean voltage (3.68 V versus Li/Li + ) energy density (559 Wh kg –1 compared with commercial (3.38 524 ). proposed expand gram-grade scale was also applicable recovery, thus closed-loop between next generation materials. Techno-economic analysis shows that potentially high economic benefits, while providing sustainable approach value-added utilization waste
