Abstract: A battery recycling process recovers lithium from nickel-rich cathode material in a recycling stream of end-of-life batteries. A dilute acid leach of a high nickel content cathode material contains a mixture of sulfuric acid based on a molar quantity of lithium in the cathode material. The highly selective leach generates a lithium rich solution with a small amount of nickel removable by nanofiltration to achieve a highly efficient recovery of the lithium contained in the recycling stream. A quantity of the leach acid based on the lithium content and a quantity of water based on a total black mass of the recycling stream results in a highly selective, near pure lithium leach when the recycling stream results from high nickel NMC batteries such as 811.
