Abstract
A method of producing a composite active material having an active material and a coat layer containing an ion conductive oxide and formed on a surface of the active material, including: applied film forming step of forming an applied film by applying a coating liquid for coat layer, containing an alkoxide compound as a raw material of the ion conductive oxide, on a surface of the active material under an atmosphere of lower dew-point temperature than dew-point temperature where the active material deteriorates; hydrolysis promoting step of promoting hydrolysis of the alkoxide compound by exposing the applied film under an atmosphere of higher dew-point temperature than dew-point temperature in the applied film forming step; and heat-treating step of forming the coat layer by heat-treating the applied film after the hydrolysis promoting step.
