Abstract

Disclosed is a doped lithium titanate and its use as an electrode in a battery. Further disclosed is a method for making an alkali metal titanate, which method includes mixing an alkali metal compound and a titanium compound, impact milling the mixture, and heating the milled mixture for a time at a temperature, which is sufficient to convert the mixture to the alkali metal titanate. The alkali metal compound can be in the form of Li2CO3 and the titanium compound can be in the form of TiO2. A dopant may be included in the mixture.
