Water-free titania-bronze thin films with superfast lithium-ion transport.

ABSTRACT

Using pulsed laser deposition, TiO2 (-) B and its recently discovered variant CaTiO2 (-) 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.
