Abstract: Cathode material from exhausted lithium ion batteries are dissolved in a solution for extracting the useful elements Co (cobalt), Ni (nickel), Al (Aluminum) and Mn (manganese) to produce active cathode materials for new batteries. The solution includes compounds of desirable materials such as cobalt, nickel, aluminum and manganese dissolved as compounds from the exhausted cathode material of spent cells. Depending on a desired proportion, or ratio, of the desired materials, raw materials are added to the solution to achieve the desired ratio of the commingled compounds for the recycled cathode material for new cells. The desired materials precipitate out of solution without extensive heating or separation of the desired materials into individual compounds or elements. The resulting active cathode material has the predetermined ratio for use in new cells, and avoids high heat typically required to separate the useful elements because the desired materials remain commingled in solution.

Abstract: A battery recycling process recovers lithium from nickel-rich cathode material in a recycling stream of end-of-life batteries. A dilute acid leach of a high nickel content cathode material contains a mixture of sulfuric acid based on a molar quantity of lithium in the cathode material. The highly selective leach generates a lithium rich solution with a small amount of nickel removable by nanofiltration to achieve a highly efficient recovery of the lithium contained in the recycling stream. A quantity of the leach acid based on the lithium content and a quantity of water based on a total black mass of the recycling stream results in a highly selective, near pure lithium leach when the recycling stream results from high nickel NMC batteries such as 811.

Abstract: A recycling and synthesis of charge material for secondary batteries generates single-crystal charge materials for producing batteries with greater charge cycle longevity. Charge material particles undergo a heating for fusing or enhancing grain boundaries between polycrystalline particles. The resulting, more well-defined grain boundaries are easily etched by a relatively weak mineral acid solution. The acid solution removes material at the grain boundaries to separate secondary particles into primary particles along the grain boundaries. The resulting single crystal (monocrystalline) charge material particles are washed and filtered, and typically re-sintered to accommodate any needed lithium (lithium carbonate), and result in a charge material with larger surface area, higher lithium diffusivity and lower cation ordering.

Abstract: Lithium-ion battery (LIB) recycling is considered as an important component to industry sustainability. A massive number of LIBs in portable electronics, electric vehicles and grid storage will eventually end up in wastes, leading to serious economic and environmental problems. Hence, tremendous effort has been made to improve hydrometallurgical recycling process since it is the most promising option for handling end-of-life LIBs owing to its wide applicability, low cost and high productivity. Despite these advantages, some extra elements (Al, Fe, C, F, etc.) remain as impurities in the removal process and remain in the solution, presenting a challenge to obtaining high-quality cathode material. This approach demonstrates the improved electrochemical performance by adding potential impurities in the leaching solution.

Abstract: A method for recycling anode materials from a comingled recycling stream derived from exhausted Li ion batteries includes receiving a precipitate quantity remaining from a cathode recycling stream. This precipitate is almost exclusively graphite used for the anode material in the recycled batteries. The precipitate results from an acid leach of charge material from the lithium battery recycling stream. A strong acid is added to the precipitate for removal of residual cathode and separator materials and the mixture heated. The strong acid removes residual aluminum oxide from the separator by transformation to aluminum sulfate. Washing the acid treated precipitate removes water soluble contaminants, such as the aluminum sulfate reacted from the aluminum oxide and sulfuric acid, to generate substantially pure graphite. Any residual material remaining from the cathode recycling phase is also removed.
