Honeycomb-like amorphous VPO4/C spheres with improved sodium storage performance as anode materials for sodium-ion batteries

In this article, honeycomb-like amorphous VPO 4 /C spheres were successfully synthesized via a sol-gel combined hydrothermal route and then tested as anode materials for sodium-ion batteries. After characterized by structure analysis, morphological observation, and composition determination, the pre...
