Li3V2(PO4)3 powders were prepared by spray pyrolysis under various conditions of gas atmosphere, preparation temperature, and carrier gas flow rate. The precursor powders had a submicrometre size and spherical shape irrespective of their preparation conditions. The morphologies and crystal structures of subsequently post-treated powders varied with the preparation conditions: 1300 οC with a flow rate of 20 L minute-1 under 10% H2/N2 reducing gas produced spherical, pure Li3V2(PO4)3 particles. Li3V2(PO4)3 powder prepared under the optimum conditions showed a maximum initial discharge capacity of 144 mAhg-1.
