Vanadium oxide nanorings: Facile synthesis, formation mechanism and electrochemical properties

Enhanced lithium storage of mesoporous vanadium dioxide(B) nanorods by reduced graphene oxide support

“…The transition-metal oxides have attracted extensive attention as cathode materials for lithium ion battery [2][3][4][5][6] . Among these, vanadium oxide has been considered as one of the most promising cathodes, because of its layered structure and variable oxidation (from + 2 to + 5) states [7,8] . In VO x based materials in which the atoms link each other by covalent bonds to form two dimensional layers that are stacked together through the weak Vander Waals interaction.…”

Synthesis of $$\hbox {V}_{2} \hbox {O}_{5}$$ V 2 O 5 nanoparticles: cathode materials for lithium-ion batteries

“…In recent years vanadium oxide-based materials have received great attention for applications in lithium-ion batteries (LIBs) due to their special structural characteristics. Vanadium oxides usually have different elemental composition, abundant oxidation states and various coordination polyhedral structures which entail the control of structural parameters to further improve their structure-directed properties [1][2][3]. These vanadium oxides show both p-type and n-type conductivity depending on the substrate and temperature.…”
