  • Lithium-ion batteries recycling process
    Patent number: 11508999
    Abstract: It is provided a process for recycling lithium ion batteries comprising shredding the lithium-ion batteries and immersing residues in an organic solvent; feeding the shredded batteries residues in a dryer producing a gaseous organic phase and dried batteries residues; feeding the dried batteries residues to a magnetic separator removing magnetic particles; grinding the non-magnetic batteries residues; mixing the fine particles and an acid producing a metal oxides slurry and leaching said metal oxides slurry; filtering the leachate removing the non-leachable metals; feeding the leachate into a sulfide precipitation tank; neutralizing the leachate; mixing the leachate with an organic extraction solvent; separating cobalt and manganese from the leachate using solvent extraction and electrolysis; crystallizing sodium sulfate from the aqueous phase; adding sodium carbonate to the liquor and heating up the sodium carbonate and the liquor producing a precipitate of lithium carbonate; and drying and recuperating the
