Abstract

The present invention relates to a method for recovering metals from a black mass from spent lithium-ion batteries. In particular, it relates to a method for leaching Co, Ni and Li from a solid S obtainable from a black mass from spent Li-ion batteries, said solid S comprising Ni, Co, Mn and Li, said method comprising contacting the solid S with a sulfur-containing inorganic peracid, such as Caro's acid (peroxymonosulfuric acid), thereby obtaining a solution C comprising Co, Ni, and Li on the one hand, and a solid S" comprising Mn on the other hand.
