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.

A method of producing a cathode material precursor having low levels of Cu impurities is described. Heat treating a black mass from a recycled lithium-ion battery stream, wherein the black mass comprises copper metal and cathode material comprising nickel, followed by leaching of the heat-treated black mass with an aqueous acid forms an acidic aqueous leach solution comprising nickel metal, cathode metal salts, and copper salts. The copper salts have been found to react with the nickel metal in the aqueous leach solution to form copper metal, which can be readily removed from the acidic aqueous leach solution. Coprecipitation of the cathode metal salts and the nickel salts form nearly Cu-free cathode material precursor.

CURING PROCESS FOR SURFACE DEFECTS OF CATHODE MATERIAL
A curing process for cathode material alleviates surface defects on particles of the cathode material for improving battery performance. Heat treating a granular form of the cathode material in a flow of an oxygen-containing gas removes surface defects on the cathode material particles that have been mechanically deagglomerated. This results in significant improvement in both the rate of charge/discharge and the number of recharge cycles.
A Li-ion cathode material is prepared by a multi-stage lithiation process that separates a total amount of lithium called for by the recycled battery to be used in a series of sintering stages. A leaching, ratio adjustment and coprecipitation sequence forms a cathode precursor having a predetermined ratio of metallic elements from a comingled recycling stream of Li-ion batteries. The precursor is sintered with a lithium salt in a sequence of stages, each having a portion of the total lithium quantity, for a predetermined duration and temperature.

BATTERY CELL DISCHARGE SYSTEM AND METHOD OF DISCHARGING CELLS
Forced discharge of Li-ion batteries for recycling extracts residual electrical energy from the battery cells to avoid sudden and unexpected release of residual energy during recycling. A battery cell containment device applies a physical restraint to one or more battery cells, and engages positive and negative terminals on the cells for electrical communication. A cooling medium flows through the containment for thermal transfer of excess heat generated during the discharge. Depending on the residual charge remaining in the battery cells, excess electrical energy is discharged thought the positive and negative terminals to a state of zero charge. A reverse voltage forces current through the anode to being the battery to a zero-energy state. The reverse voltage continues until internal short circuits resulting from degradation of current collectors in the battery render it benign.

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.
A hydrometallurgical coprecipitation process for leached cathode materials includes adjusting a pH and agitation of an aqueous acidic leach solution in successive stages of a multi-stage reactor system for generating coprecipitated particles of a targeted morphology, particle size range, and surface characteristics. The aqueous acidic leach solution (leach solution) initially forms seed particles based on increasing pH. In successive stages, the pH and the stirring rate are varied for growing the seed particles into progressively larger particles as additional leach solution is introduced.

A method of producing a purified graphite from a recycled battery stream for use in as anode material in Li-ion batteries is described. The method comprises a leaching step to obtain a precipitate comprising graphite by filtration, which is then iteratively roasted as a slurry with an aqueous solution of a hydroxide base and subsequently washed to form a purified graphite.
A recycling process for Lithium-ion (Li-ion) batteries includes a selective leach of charge material metals followed by impurity control for effecting microstructures such as a pore volume and surface area for optimal structures and charge performance. Particle characteristics having a favorable effect on performance correlate with soluble impurities in a recycling leach solution formed from spent charge material in a battery recycling stream. Spent batteries yield a black mass of agitated, comingled cathode material, anode material and current collectors. Leaching of the black mass yields a recycling solution of charge material metals and impurities. Selective adjustment of these impurities through adding and/or separating soluble ions in the solution drives formation of internal voids, surface area and pore volume in the resulting cathode material.

A method to recycle graphite from lithium and sodium-ion batteries. Graphite from the batteries first is treated in an aqueous solution of strong base at a temperature range between about 100° C. and about 250° C., a pressure range between about 0.9 bar and about 20 bar, at a solid-to-liquid ratio of from about 1-to-1 to about 1-to-4. The treated graphite is then washed, filtered, and then treated with a mineral acid (e.g., hydrochloric acid). The purified graphite is then coated with amorphous carbon at a weight percentage range between 0.5 wt % and about 20 wt %. The recycled graphite yielded by the method routinely achieves a purity >99.9%, a specific area of less than or equal to about 10 m2/g.

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.
