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.

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.
