Abstract
Graphite-anchored lithium vanadium oxide (Li1.1V0.9O2) has been synthesized via a “one-pot” in situ
method. The effects of the synthesis conditions, such as the ratio of reaction components and calcination
temperature, on the electrochemical performance are systematically investigated by means of
scanning electron microscopy (SEM), X-ray diffraction (XRD), electrochemical impedance spectroscopy
(EIS), galvanostatic discharge/charge tests and differential scanning calorimetry (DSC). Compared with
the simple mixture of graphite and lithium vanadium oxide, the graphite-anchored lithium vanadium
oxide delivers an enhanced reversible capacity, rate capability and cyclic stability. It also shows better
thermal stability.
