  "textContent": "The present invention provides a method for producing a high quality positive electrode active material for lithium ion batteries at low cost and at excellent production efficiency. The method for producing a positive electrode active material for lithium ion batteries includes a step of firing a powder of lithium-containing carbonate that is a precursor for positive electrode active material for lithium ion batteries in a rotary kiln. In the step, a temperature at a powder feed part inside of the rotary kiln is kept at 500°C or more.",
