【 摘 要 】

In this paper, fibrous-shaped of V6O13 were successfully synthesized via V2O5 and ethanol as reactants through the method of magnetic stirring in the oil bath, Compared to the prepared sample without mechanical force-driven, the sample prepared by this method has a fibrous morphology with good dispersion. It can be seen that as the speed increases, the width of the fibers decreases, the fiber length increases after SEM tests. After the electrochemical tests, it can be seen that the attrition rate of capacity will be successfully inhibited in the process of charging and discharging when the fibrous-shaped V6O13 as a lithium ion batteries cathode materials. When the stirring rate was 0 rpm and possessed a reversible capacity of 72 mAh/g after 50 deep cycles. By contrast, the stirring rate was 1200 rpm and possessed a reversible capacity of 102 mAh/g after 50 deep cycles. It increased 41.6%.
