Abstract
A method for producing a lithium metal composite oxide, in which, in a calcining step of calcining a substance to be calcined using calcining means, the substance to be calcined is a mixture of a metal composite compound and a lithium compound or a mixture raw material containing a reactant of the metal composite compound and the lithium compound, a content rate of Li in the substance to be calcined is more than 5 mass % and 10 mass % or less, the calcining means includes an inner wall, a main material of the inner wall is an alloy, the alloy contains Ni and Al, a content rate of the Ni with respect to a total amount of the alloy is 93 mass % or more and 95 mass % or less, and a content rate of the Al with respect to the total amount of the alloy is 3 mass % or more and 5 mass % or less.
