LIB recycling sees metallurgical and mechanical processes used separately, or in combination, to recover valuable metals and materials from end of life and production scrap LIBs. Concerns regarding the efficiency of processing and the need to sustainably dispose and recover potentially hazardous materials sets the stage for huge LIB recycling opportunities.
The Neometals LIB recycling process targets the predominant LIB chemistries, with LCO (lithium cobalt oxide) and NMC/NCA (nickel manganese cobalt/nickel cobalt aluminium) cathode batteries targeted from electric vehicles, energy storage systems and from consumer electronics.
While the use of LIB anode materials generally remains constant, cathode compositions tend to differ based on end use application and performance requirements. The key minerals targeted for recovery by Neometals are as follows:
- Graphite; and
Plastics, aluminium foil (the cathode substrate) and copper foil (the anode substrate) are separated early. The balance of materials are recovered and refined into industrial and high purity chemicals for sale, where possible, directly back into the LIB supply chain.
