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 uniquely structured electrochemically active particles characterized by a first electrochemically active material and a second electrochemically active material disposed about the first material whereby at least the second material includes a modifier present as a continuous transition concentration gradient from the first material into the second material whereby the concentration is lower in the first material than the second material. Also provided are processes of producing the particle and electrochemical cells incorporating the particles as a positive electrode material in a cathode.

Abstract: Provided are processes for the formation of electrochemically active materials such as lithiated transition metal oxides that solve prior issues with throughput and calcination. The processes include forming precursor materials into agglomerates prior to calcination. The use of the agglomerates improves gas flow into and out of the materials thereby improving calcination results, electrochemical properties of the resulting materials, and allows for use of high temperature kilns not previously suitable for such materials thereby lowering production costs.

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 the formation of electrochemically active materials such as lithiated transition metal oxides that solve prior issues with throughput and calcination. The processes include forming the materials in the presence of a processing additive that includes potassium prior to calcination that produces active materials with increased primary particle grain sizes.
