Abstract
A method for manufacturing a positive electrode active material for a lithium ion secondary battery involves reacting at least 95 mass % of a lithium compound through a heat treatment step using a rotary firing furnace and having a batch firing process for heating a precursor while rolling the same in a heating region in a furnace tube, wherein the batch firing process has: a tilted input stage for tilting the furnace tube and inputting the precursor from an inlet of the firing furnace; a horizontal firing stage for performing firing while making the furnace tube horizontal; and a tilted discharge stage for tilting the furnace tube and discharging a fired powder from an outlet of the firing furnace.
