Abstract

A method of manufacturing a positive electrode material for a lithium ion secondary battery includes: firing a mixture containing a lithium compound, a nickel-containing complex compound, and a molybdenum compound, to obtain first particles containing a lithium transition metal complex oxide having a composition in which a ratio of a number of moles of nickel to a total number of moles of metals other than lithium is greater than 0.6 and less than 1; and bringing the first particles into contact with a liquid medium in such that a solid content concentration of the first particles is in a range of 20 mass % to 80 mass % to remove a part of molybdenum element contained in the first particles to obtain second particles.
