PROCESS FOR MAKING A PARTICULATE (OXY)HYDROXIDE OR OXIDE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18548011 titled 'PROCESS FOR MAKING A PARTICULATE (OXY)HYDROXIDE OR OXIDE

The process described in the patent application involves creating a particulate (oxy)hydroxide, carbonate, or oxide of a transition metal (TM) such as nickel, along with at least one metal chosen from cobalt, manganese, and aluminum. This is achieved by combining various aqueous solutions containing salts of the metals in a continuous reactor and separating the resulting particles from the liquid.

The process involves combining aqueous solutions of metal salts in a continuous reactor.
The metals involved include nickel and at least one of cobalt, manganese, or aluminum.
Solid-liquid separation is used to remove the particles from the liquid.
Alkali metal hydroxide or carbonate, as well as ammonia or organic acids, may be included in the process.
The method allows for the production of particulate (oxy)hydroxides, carbonates, or oxides of transition metals.

Potential Applications: - Production of catalysts - Manufacturing of battery materials - Synthesis of pigments and dyes
