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.
