Facile synthesis of Montroseite VOOH, Paramontroseite VO 2 and V 2O 3-VO 2 carbonaceous core-shell microspheres
Abstract
Hydrothermal carbonization of sucrose was used to controllably synthesize Montroseite VOOH and Paramontroseite VO 2 nanoparticles carbonaceous core-shell microspheres. After calcinations, V 2O 3-VO 2-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 VO 2 counterpart, while the content of V 2O 3 had some large effects on the electrochemical properties of V 2O 3-VO 2C core-shell microspheres.
