Abstract
The invention relates to hydrometallurgical method for recovering metals from spent energy storage devices. The method comprises combining aqueous hydrobromic acid leach solution and an electrode material of spent energy storage devices in a reaction vessel, dissolving the metals contained in the electrode material to form soluble metal bromide salts, removing elemental bromine, if formed, from the reaction vessel, separating insoluble material, if present, from the leach solution to obtain a metal-bearing solution and isolating one or more metals from said metal-bearing solution.
Claims17
Hydrometallurgical method for recovering metals from spent energy storage devices, comprising combining aqueous hydrobromic acid leach solution and an electrode material of spent energy storage devices in a reaction vessel, wherein the electrode material comprises mixed metal oxide with one or more transition metals, one of which is managanese, dissolving the metals contained in the electrode material to form soluble metal bromide salts, removing elemental bromine from the reaction vessel, separating insoluble material, if present, from the leach solution to obtain a metal-bearing solution and isolating one or more metals, one of which is manganese, from said metal-bearing solution.
