Abstract
Disclosed are: a novel lithium titanate; and a method for producing the novel lithium titanate. Specifically disclosed is a compound that has a chemical composition represented by the general formula (1): LiTiO, or the compound additionally containing copper and/or tin. The compound represented by the general formula (1) is synthesized by causing a lithium compound to react with a compound that has a chemical composition represented by the general formula (2): HTiOin a liquid phase so that some of hydrogen ions contained in the compound represented by the general formula (2) are substituted by lithium ions, and then carrying out solid-liquid separation and thermal dehydration. An electricity storage device which uses, as a constituent member, an electrode that contains an electrode active material produced from the compound represented by the general formula (1) has excellent charge and discharge cycle characteristics, especially excellent charge and discharge cycle characteristics at high temperatures, and is expected to have high capacity.
