PRODUCTION METHOD FOR LITHIUM ION SECONDARY BATTERY POSITIVE ELECTRODE ACTIVE MATERIAL, LITHIUM ION SECONDARY BATTERY POSITIVE ELECTRODE ACTIVE MATERIAL, ELECTRODE, AND SOLID-STATE LITHIUM ION SECONDARY BATTERY

WIPO Patent Application WO/2023/153344

A1

This production method is for a lithium ion secondary battery positive electrode active material that is provided with a lithium metal composite oxide and a coating layer for coating at least a part of one particle of the lithium metal composite oxide, the method comprising a coating step for bringing the lithium metal composite oxide into contact with a coating liquid for forming the coating layer by using a coating device equipped with a two-fluid nozzle. The lithium metal composite oxide satisfies (A). The coating device jets each of the coating liquid and high-pressure air flow in the coating step. The high-pressure air flow satisfies (B).

JP4774661	A method for producing a lithium transition metal composite oxide, a positive electrode material for a lithium secondary battery, a positive electrode for a lithium secondary battery and a lithium secondary battery, and a lithium transition metal composite oxide.
