Designing the multidimensional nanomaterial hybrid composite electrode is an effective approach to improve the electrochemical conductivity, structural stability, and Na-ion storage capacity of the anode for sodium-ion batteries. Herein, through solvothermal reaction and subsequent calcination, the V 2 O 3 /C nanocomposite is synthesized which served as a capable Na-ion host. Zero-dimensional V 2 O 3 nanoparticles are in situ generated on a two-dimensional carbon layer to constitute a firm structure with high electrical conductivity. The V 2 O 3 /C nanocomposite shows desirable cycle performance (216 mA h g −1 at 0.5 A g −1 after 1000 cycles) and remarkable rate ability (205 mA h g −1 at 2 A g −1 ). Meanwhile, the Na-ion storage mechanism indicates that the storage capacity is mainly dominated by the capacitance behavior, thus enhancing the rate ability and cycle performance. This work demonstrates the importance of constructing a nanocomposite on electrode materials and displays a viable approach to fabricate nanocomposite electrode materials for metal-ion batteries.
