A selective leaching process is proposed to recover Li, Fe, and P from the cathode materials of spent lithium iron phosphate (LiFePO4) batteries. It was found that using stoichiometric H2SO4 at a low concentration as a leachant and H2O2 as an oxidant, Li could be selectively leached into solution while Fe and P could remain in leaching residue …

Arumugam Manthiram and John B. Goodenough first identified the polyanion class of cathode materials for lithium ion batteries. LiFePO 4 was then identified as a cathode material belonging to the polyanion class for use in batteries in 1996 by Padhi et al. Reversible extraction of lithium from LiFePO 4 and insertion of lithium into FePO 4 was demonstrated. Neutron diffraction confirmed that LFP was able to ensure the security of large input/output current of lithium batteries.
