Sodium-ion batteries (SIBs) hold great promise as power sources because of their low cost and decent electrochemical behavior. Nevertheless, the poor rate performance and long-term cycling capability of anode materials in SIBs still impede their practical application in smart grids and electric vehicles. Herein, we design a delicate method to embed WS2 nanosheets into lotus rhizome-like heteroatom-doped carbon nanofibers with abundant hierarchical tubes inside, forming WS2@sulfur and nitrogen-doped carbon nanofibers (WS2@S/N-C). The WS2@S/N-C nanofibers exhibit a large discharge capacity of 381 mA h g-1 at 100 mA g-1, excellent rate capacity of 108 mA h g-1 at 30 A g-1, …

Heterostructures are attractive for advanced energy storage devices due to their rapid charge transfer kinetics, which is of benefit to the rate performance. The rational and facile construction of heterostructures with satisfactory electrochemical performance, however, is still a great challenge. Herein, ultrafine hetero-CoO/Co3S4 nanoparticles embedded in N-doped carbon frameworks (CoO/Co3S4@N-C) are successfully obtained by employing metal-organic frameworks as precursors. As anodes for sodium ion batteries, the CoO/Co3S4@N-C electrodes exhibit high specific capacity (1029.5 mA h g−1 at 100 mA g−1) and excellent rate capability (428.0 mA h g−1 at 5 A g−1), which may be attributed to their enhanced electric …
