Furthermore, it is worth noting that the leaching residue FePO 4 can be used to regenerate Fe 2 P 2 O 7 and serve as anode materials for lithium-ion batteries. Thermodynamic calculations and analysis revealed that HCOOH, combined with H 2 O 2, exhibits excellent lithium selectivity, allowing for the selective leaching of lithium.
The recycling of cathode materials from spent lithium-ion battery has attracted extensive attention, but few research have focused on spent blended cathode materials. In reality, the blended materials of lithium iron phosphate and ternary are widely used in electric vehicles, so it is critical to design an effective recycling technique. In this …
However, rare and valuable metals, such as Co, Ni, and Mn remain in the discharged residue after subjecting the R–R–R powder to hydrothermal lithium extraction …
98.6wt% lithium was recovered as lithium carbonate (Li 2CO 3). Already the crude product has battery grade-quality (>99.8wt%), i.e., there is no further refining needed. The other valuable metals Co, Cu, Mn, and Ni remain in the solid residue [2]. Sustainable use of LIBs means closing the loop, thus full recovery of all valuable metals.
By adding alkali (KOH/Ca(OH) 2, 20 %), hexafluorophosphate in the electrolyte was transformed into fluoride and phosphate in the residue, thereby reducing the device''s corrosion from fluorine-containing gas. This study provides a viable approach for managing the residual electrolyte in the waste lithium battery recovery process.
