Laboratory study demonstrates ≥98% recovery of lithium and cobalt from batteries using ultrasound and weak organic acids, suggesting an efficient sustainable recycling pathway.
Ultrasound-assisted extraction of metal ions from Lithium batteries with weak organic acids is reported. Leaching reached ≥98% Li and Co recovery due to improved residue layer diffusion and mass transfer, illustrated by the shrinking core model.
