Process for the recovery of lithium and other metals from waste lithium ion batteries

This invention describes a method to recover valuable metals, specifically nickel, cobalt, and lithium, from discarded lithium-ion batteries. The process involves taking shredded battery material, which can be a powder or a liquid suspension, and treating it with a special solvent to separate out the lithium. The remaining solid material, rich in nickel and cobalt, is then melted in a furnace to recover these metals as an alloy.

Why it matters: The significant increase in global lithium-ion battery production since 2020 has created a larger, more urgent need for robust recycling processes to recover critical materials like lithium, nickel, and cobalt.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSmelting furnace, chemical processing equipment
