The gel-typed electrolyte batteries, using Li3V2(PO4)3 as cathode and lithium metal as anode, were prepared. The specific capacity of the battery is improved by doping α-Al2O3 particles in polymer gel electrolyte. However, the specific capacities are only 83% and 42% of the theoretical value, when 1 C and 5 C charging-discharging rates are used, respectively. After charging-discharging 100 times using 1 C or 5C charging rate, the coulomb efficiencies are still 100%. This indicates the structural stable of Li3V2(PO4)3 during charging-discharging process.
