Electrolytic V2O5, called e-V2O5, can be prepared by oxidative electrodeposition from an aqueous vanadyl sulfate solution. It can be dehydrated at T?180°C, while transformation to orthorhombic a-V2O5 occurs at T>180°C.
Various preparation conditions have been used in
order to obtain e-V2O5 cathode materials with various
physico-chemical characteristics. This study focusses on the understanding
of the relationships between such characteristics and the lithium intercalation
behavior.
