    Abstract: The invention relates to hydrometallurgical method for recovering lithium and one or more transition metals from spent lithium ion batteries, comprising: treating an electrode material of the batteries in an alkaline solution to dissolve lithium in said solution; separating from the alkaline solution a solid phase consisting of lithium-depleted electrode material; recovering lithium from said alkaline solution; leaching the lithium-depleted electrode material with an acid leach solution to dissolve one or more transition metals of the electrode material in the leach solution; separating insoluble material, if present, from the leach solution to obtain metal-bearing aqueous solution and isolating one or more transition metal(s) and optionally the remainder of the lithium from said metal-bearing aqueous solution.
