Abstract

Provided is a lithium titanate powder for an electrode of an energy storage device, the lithium titanate powder comprising LiTiOas a main component, wherein, when the volume surface diameter calculated from the specific surface area determined by the BET method is represented as Dand the crystallite diameter calculated from the half-peak width of the peak of the (111) plane of LiTiOby the Scherrer equation is represented as D, Dis 0.1 to 0.6 μm, Dis greater than 80 nm, and (D/D(μm/μm)) the ratio of Dto Dis 3 or less. Also provided are an active material including the lithium titanate powder and an energy storage device using the active material.
