  • Process for recovering metals from recycled rechargeable batteries
    Patent number: 12000014
    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.
    Type: Grant
    Filed: August 4, 2019
    Date of Patent: June 4, 2024
    Assignee: BROMINE COMPOUNDS LTD.
    Inventors: Or Press Frimet, Mohamad Masarwa, Yaniv Englert, Eyal Barnea
  • Quarternary ammonium halides for treating halogen contamination
    Patent number: 11679293
    Abstract: The invention relates to a method for treating emergency spill or leak of halogen which is bromine or chlorine, comprising contacting an aqueous solution of quaternary ammonium halide with the halogen.
    Type: Grant

  • A PROCESS FOR RECOVERING METALS FROM RECYCLED RECHARGEABLE BATTERIES
    Publication number: 20230080556
    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.
