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 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: 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.
