| Abstract Scope |
Aiming to recover critical materials from waste batteries, we have developed a series of operations to extract individual metals from the end-of life solid mixture based on their electrochemical (EC) and chemical properties. Our large-scale EC-leaching process isolates graphite and metallic copper by electricity, and generates a leachate solution of metals.[1] This leachate can contain aluminum and iron that are removed by pretreatment processes. Then, the remaining critical metals can be individually extracted through other extraction operations, including solvent extraction, ion-exchange, precipitation, and electrochemical dialysis. Through these methods, we have successfully developed a feasible and flexible recovery of critical materials and high purity metal salts from recycled waste lithium-ion battery materials.
