description The present invention relates to lithium titanate materials suitable for use in electrochemical applications, and methods for their production. The materials of the present invention are particularly suitable as electrode (e.g. anode) materials, and as lithium ion conducting membranes. Accordingly, the materials of the present invention may find particular utility as battery materials, e.g. in lithium ion and/or lithium air batteries. In particular, the present invention provides a method for the preparation of lithium titanate, wherein a precursor mixture comprising a solvent, a lithium precursor and a titanium precursor is subjected to flame spray pyrolysis to produce lithium titanate particles. The present inventors have found that it is possible to significantly reduce the formation of the rutile impurity phase by controlling the flame spray pyrolysis process.
