Abstract: Disclosed is a process for removing impurities from an intermediate product in battery material production including a) contacting a first intermediate product with a first aqueous medium to obtain a second intermediate product; and b) contacting the second intermediate product with a stream of a second aqueous medium until a conductivity of the stream of the second aqueous medium after contacting the second intermediate product is below about 1,000 micro-Siemens per centimeter (μS/cm).

Abstract: Provided are processes for extracting lithium and optionally nickel from a Nickel(II)/Lithium(I) (Ni2+/Li+) solution. The extraction is optionally performed in a series of steps with counterflow of aqueous and organic flows to thereby produce a lithium poor solution. The lithium poor solution may be treated so that remaining Ni in the lithium poor solution may be directly precipitated therefrom in the form of a Ni salt. Once complete, the process provides for recoverable nickel and/or lithium that may be recycled into batteries or sold for other uses.

Abstract: Provided are processes for extracting nickel and lithium from a Ni2+/Li+ solution. The process for extracting nickel and lithium includes providing a Ni2+/Li+ solution comprising an amount of lithium and an amount of nickel, treating the Ni2+/Li+ solution with an alkaline agent to adjust the pH of the Ni2+/Li+ solution to between about 1.0 to about 10.0, and treating the Ni2+/Li+ solution with a nickel selective extractant, the nickel selective extractant suitable to extract nickel from the Ni2+/Li+ solution at said pH to thereby produce a Li+ solution with less than 1000 parts per million Ni2+. Once complete, the process provides for recoverable nickel and/or lithium that may be recycled into batteries or sold for other uses.

Abstract: Disclosed is a process for producing a battery material including contacting a first intermediate product of a battery material with an acidic medium under conditions sufficient to dissolve low-lithium-containing oxide present on a surface of the first intermediate product to obtain a second intermediate product such that a weight of the second intermediate product is 0.2% to 5% less than a weight of the first intermediate product.

Abstract: Disclosed herein are methods of recycling elements, such as, e.g., lithium and/or nickel, from a solution, such as, e.g., methods of recovering reusable lithium and nickel from a waste stream produced by the delithiation of a lithium nickel oxide material.

Abstract: Disclosed herein are processes for isolating purified water from a waste stream, such as, e.g., a waste stream formed in the manufacture or recycling of batteries, and further e.g., processes for isolating purified water suitable for use in downstream industrial processes from a waste stream generated during delithiation of a lithium metal oxide material.
