description A production method for a lithium metal complex oxide is for producing a lithium metal complex oxide that contains at least nickel and that can be used for doping with lithium ions and removal of lithium ions, and the method comprises the steps: a mixing step for mixing a metal complex compound containing at least nickel with a lithium compound to obtain a mixture; a firing step for firing the mixture in an oxygen-containing atmosphere to obtain a fired product; a washing step for washing the fired product to obtain a washed product; and a thermal treatment step for subjecting the washed product to a thermal treatment, wherein, in the mixing step, the mixing is performed such that the ratio (molar ratio) of the number of moles of lithium in the lithium compound to the total number of molesof metal elements in the metal complex compound exceeds one, and the thermal treatment step is performed at a temperature increase rate of 100 DEG C/hr or more and at a maintained temperature of morethan 550 DEG C but not mo
