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.

The Si/C anode is one of the most promising candidate materials for the next-generation lithium-ion batteries (LIBs). Herein, a silicon/carbon nanotubes/carbon (Si/CNTs/C) composite is in situ synthesized by a one-step reaction of magnesium silicide, calcium carbonate, and ferrocene. Transmission electron microscopy reveals that the growth of CNTs is attributed to the catalysis of iron atoms derived from the decomposition of ferrocene. In comparison to a Si/C composite, the cycle stability of the Si/CNTs/C composite can obviously be improved as an anode for LIBs. The enhanced performance is mainly attributed to the following factors: (i) the perfect combination of Si nanoparticles and in situ grown CNTs achieves high mechanical integrity and good electrical contact; (ii) Si nanoparticles are entangled in the CNT cage, effectively reducing the volume expansion upon cycling; and (iii) in situ grown CNTs can improve the conductivity of composites and provide lithium ion transport channels. Moreover, the full cell constructed by a LiFePO4 cathode and Si/CNTs/C anode exhibits excellent cycling stability (137 mAh g–1 after 300 cycles at 0.5 C with a capacity retention rate of 91.2%). This work provides a new way for the synthesis of a Si/C anode for high-performance LIBs.
