METHOD FOR PRODUCING POSITIVE ELECTRODE ACTIVE MATERIAL FOR LITHIUM ION SECONDARY BATTERIES

WIPO Patent Application WO/2024/095979

A1

A method for producing a positive electrode active material for lithium ion secondary batteries, said method comprising: a mixing step for mixing a lithium compound and a nickel-containing substance that contains at least nickel to prepare a raw material mixture; a firing step for firing the raw material mixture in an oxidizing atmosphere to obtain a fired product; a washing step for washing the fired product obtained in the firing step to obtain a washed powder; and a boron addition step for spraying, onto the washed powder obtained in the washing step, a boron-containing solution that contains a boron-containing substance, which is at least one substance selected from among boron and boron-containing compounds.
