Application: Beta-nickel hydroxide doped with aluminum (Patent ID: US20240150196A1)
The patent by Umicore NV/SA focuses on ß-nickel hydroxide doped with aluminum ions, where the aluminum ions are evenly distributed in the crystal lattice. This material is intended for use as a precursor in the production of electrode materials for lithium-ion batteries, nickel-metal hydride batteries, and Raney nickel catalysts. The ß-nickel hydroxide described in the patent consists of secondary particles made up of agglomerated primary crystallites with a primary crystallite size of 100 Å or less, and a particle size ranging from 2 to 20 µm.
The patent also outlines a method for producing the ß-nickel hydroxide doped with aluminum ions, involving specific steps such as preparing a solution of Na2SO4, NaOH, and NH3, adding an aluminate and a nickel compound to form the ß-nickel hydroxide, and separating the final product. The method allows for the addition of cobalt ions as well, resulting in a ß-nickel hydroxide doped with both cobalt and aluminum ions. Additionally, there is an optional conditioning step with sodium hydroxide to reduce the sulfate content of the final product.
