چکیده انگلیسی
CuV2O6 is a very promising cathode material for rechargeable lithium batteries. By a soft chemistry method, CuV2O6 is successfully synthesized from V2O5 hydrogel and Cu2O powder. CuV2O6 with different degrees of crystallinity are obtained by heating CuV2O6 precursor at various temperatures. XRD, TG–DTA, TEM and SEM experiments are conducted to characterize its physical properties, and the electrochemical properties have been investigated by galvanostatic charge–discharge experiments. As a result, CuV2O6 annealed at 550 °C has smaller crystal lattice constants and better electrochemical properties compared to the sample synthesized by the conventional solid-state method.
