Title:
METHOD FOR PRODUCING NICKEL PARTICLES, METHOD FOR PRODUCING NICKEL SULFATE, AND METHOD FOR PRODUCING POSITIVE ELECTRODE ACTIVE MATERIAL FOR SECONDARY BATTERIES
Document Type and Number:
WIPO Patent Application WO/2020/066262
Kind Code:
A1
Abstract:
A process for producing nickel particles comprises the steps of: melting a nickel source to produce a melt; and powderizing molten nickel contained in the melt by an atomization method comprising atomizing a gas or an aqueous medium onto the melt, thereby producing nickel particles having purity of 90% or more. In the production process, it is also possible to melt a metal that is more likely to be oxidized than nickel together with the nickel source and then remove an oxide of the metal which is produced as the result of the melting.
