Three-dimensional TiNb₂O₇ anchored on carbon nanofiber core-shell arrays as an anode for high-rate lithium ion storage.

ABSTRACT: The control of structure and morphology in an electrode design for the development of large-power lithium ion batteries is crucial to create efficient transport pathways for ions and electrons. Herein, we report a powerful combinational strategy to build omnibearing conductive networks composed of titanium niobium oxide nanorods and carbon nanofibers (TNO/CNFs) via an electrostatic spinning method and a hydrothermal method into free-standing arrays with a three-dimensional heterostructure core/shell structure. TNO/CNF electrode exhibits significantly superior electrochemical performance and high-rate capability (241 mA h g^-1 at 10C, and 208 mA h g^-1 at 20C). The capacity of the TNO/CNF electrode is 257 mA h g^-1 after 2000 cycles at 20C, which is much
