Abstract (en)

[origin: WO2022200747A1] The invention relates to a pyrometallurgical method for recycling shredded material of end-of-life Li-ion electric vehicle batteries, and/or waste from the production of these new and defective batteries, and/or portable Li-ion batteries. The method involves adding iron, melting by adding energy, separating a slag, carrying out an oxidising treatment and separating a second slag.
