METHODS OF PRODUCING CATHODE MATERIAL PRECURSORS UTILIZING CAVITATION, AND PRODUCTS THEREOF

Abstract: a process for the production of a mixed metal hydroxide material for use as a cathode active material precursor is described, wherein the process utilizes cavitation to produce high quality materials through elimination of some processing steps and ingredients. in particular, a method of producing a mixed metal hydroxide material combining a first metal, a second metal, an oxidant and a liquid to form a reaction slurry is disclosed. the method may include applying cavitation to the liquid prior to the formation of the reaction slurry and/or applying cavitation to the liquid when the liquid is part of the reaction slurry. a method of forming an active material and a mixed metal hydroxide material for use as an active material precursor is also disclosed.
