| Abstract: | 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. |
