Abstract
Provided are a transition metal mixed hydroxide comprising an alkali metal other than Li, SO4 and a transition metal element, wherein the molar ratio of the molar content of the alkali metal to the molar content of the SO4 is not less than 0.05 and less than 2, and a lithium mixed metal oxide obtained by calcining a mixture of the transition metal mixed hydroxide and a lithium compound by maintaining the mixture at a temperature of 650 to 1000° C.
