Construction Strategy of VO@VC 1D/2D Heterostructure and Improvement of Zinc-Ion Diffusion Ability in VO (B).

VO (B) electrode material has relatively high capacity and good cycle stability. However, its poor rate performance limits its further development because of the strong interaction between zinc ions and the main lattice of VO (B). Herein, considering the design principle of rate performance improvement, we furnished a different scheme from a previous multistep method of the synthesis-modification strategy of pure VO (B).
