Abstract
Li 3V 2(PO 4) 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 °C with a flow rate of 20 L minute under 10% H 2/N 2 reducing gas produced spherical, pure Li 3V 2(PO 4) 3particles. Li 3V 2(PO 4) 3powder prepared under the optimum conditions showed a maximum initial discharge capacity of 144 mAhg 1.
