Abstract:
A process for producing lithium titanate, comprising:presintering a mixture of titanium dioxide and at least one lithium compound selected from the group consisting of lithium carbonate, lithium hydroxide, lithium nitrate, and lithium oxide, for a duration of 30 minutes to 4 hours at a temperature of at least 600Â° C. and less than 800Â° C., to yield at least one of a composition comprising TiO2 and Li2TiO3 and a composition comprising TiO2, Li2TiO3 and Li4Ti5O12; and separately sintering the composition at a temperature of from 800Â° C. to 950Â° C. in an atmosphere in which the partial pressure of oxygen gas is not more than 1 Pa.
