Abstract
A method for producing an active material composite for all-solid-state lithium secondary batteries, the active material composite having a lithium niobate-containing coating layer on an active material surface, and the production method being able to decrease the content of a nitrogen element derived from a niobic acid raw material in the coating layer of the active material composite thus produced, and to decrease the reaction resistance of an all-solid-state lithium battery using the active material composite. The active material composite production method may comprise: preparing a coating liquid containing a peroxo complex of niobium and a lithium element, by use of a niobic acid in which a content of a nitrogen element contained as an impurity is 0.1% by mass or less, and forming the lithium niobate-containing coating layer on the active material surface by use of the coating liquid.
