description | A novel complementary approach for promising anode materials is proposed. Sodium titanates with layered Na(2)Ti(3)O(7) and tunnel Na(2)Ti(6)O(13) hybrid structure are presented, fabricated, and characterized. The hybrid sample exhibits excellent cycling stability and superior rate performance by the inhibition of layered phase transformation and synergetic effect. The structural evolution, reaction mechanism, and reaction dynamics of hybrid electrodes during the sodium insertion/desertion process are carefully investigated. In situ synchrotron X‐ray powder diffraction (SXRD) characterization is performed and the result indicates that Na(+) inserts into tunnel structure with occurring solid solution reaction and intercalates into Na(2)Ti(3)O(7) structure with appearing a phase transition in a low voltage. The reaction dynamics reveals that sodium ion diffusion of tunnel Na(2)Ti(6)O(13) is faster than that of layered Na(2)Ti(3)O(7). The synergetic complementary properties are significantly conductive to enhance electrochemical behavior of hybrid structure. This study provides a promising candidate anode for advanced sodium ion batteries (SIBs). |
