Abstract
An active material powder includes an active material particle, and a coating layer. The coating layer contains LiNbOand has pores. When a total volume of pores having a diameter of 2 nm to 7 nm and a total volume of pores having a diameter of 2 nm to 200 nm are respectively represented by Vand V, V/Vis 0.185 or less. In addition, a method of producing an active material powder includes: obtaining, with a fluidized bed granulating-coating machine, a powder including an active material particle to which an alkoxide compound is attached; and promoting hydrolysis of the alkoxide compound by exposing the powder to a humidified inert gas atmosphere. An intake-gas temperature of the fluidized bed granulating-coating machine is 100° C. or higher. A time during which the powder is exposed to the humidified inert gas atmosphere is four hours or longer.
