文摘

Hydrothermal carbonization of sucrose was used to controllably synthesize Montroseite VOOH and Paramontroseite VO₂ nanoparticles carbonaceous core-shell microspheres. After calcinations, V₂O₃-VO₂-C core-shell microspheres were obtained. When they were used as cathode materials in lithium-ion battery (LIB), it was found that Montroseite VOOH carbonaceous core-shell microspheres exhibited higher discharge capacity than Paramontroseite VO₂ counterpart, while the content of V₂O₃ had some large effects on the electrochemical properties of V₂O₃-VO₂C core-shell microspheres.
