Thus, stable structured materials with large tunnels can provide long cycle life to help establish high-performance batteries. Herein, the electrochemical properties and associated reaction mechanism of a stable structured Na2MoO4 anode material are investigated in sodium-ion batteries. Na2MoO4/C nanocomposite is prepared using the ball-milling method and size of the particles is reduced from micro- to nanometers. The composite electrode shows high cycling stability exhibiting a specific capacity of 84 mAh g(-1) at the first cycle and 81 mAh g(-1) at the 1000th cycle, demonstrating a capacity retention of >96%. The reaction mechanism is evaluated with synchrotron-based in situ XRD and X-ray absorption spectroscopy. The results thus obtained, imply that the Na2MoO4/C anode shows low volume change (0.68%) in crystal structure upon cycling and Mo-O tetrahedral coordination is reversibly affected by the sodium insertion/extraction process.
