Hydrogenated Li(4)Ti(5)O(12) nanowire arrays for high rate lithium ion batteries.

Self-supported Li(4) Ti(5) O(12) nanowire arrays with high conductivity architectures are designed and fabricated for application in a Li-ion battery. The Li(4) Ti(5) O(12) nanowire arrays grow directly on Ti foil by a facile solution-based method, further enhancing Li-ion storage properties by creating Ti(3+) sites through hydrogenation. This configuration ensures that every Li(4) Ti(5) O(12) nanowire participates in the fast electrochemical reaction, enabling remarkable rate performance and a long cycle life.
