Using pulsed laser deposition , TiO 2 ‐ B and its recently discovered variant Ca:TiO 2 ‐ B (CaTi5O11) are synthesized as highly crystalline thin films for the first time by a completely water‐free process. Significant enhancement in the Li‐ion battery performance is achieved by manipulating the crystal orientation of the films, used as anodes, with a demonstration of extraordinary structural stability under extreme conditions.
