Title:
METHOD FOR PRODUCING POSITIVE ELECTRODE ACTIVE MATERIAL FOR LITHIUM ION SECONDARY BATTERIES
Document Type and Number:
WIPO Patent Application WO/2024/095981
Kind Code:
A1
Abstract:
This method for producing a positive electrode active material for lithium ion secondary batteries comprises: a mixing step in which a lithium compound and a nickel-containing material that contains at least nickel are mixed with each other, thereby preparing a starting material mixture; a firing step in which the starting material mixture is fired in an oxidizing atmosphere, thereby obtaining a fired material; and a boron addition step in which a boron-containing solution that contains at least one boron-containing material selected from among elemental boron and a boron-containing compound is sprayed onto the fired material obtained in the firing step.
