We report on a novel synthetic method of microwave processing with a domestic microwave oven to prepare LiFePO4 cathode materials. We also studied and report on the electrochemical properties of the resultant products. XRD revealed that a single phase LiFePO4 powder can be synthesized quickly and easily by microwave processing. The initial discharge capacity of a cell assembled with the powder was 125mAh/g at 60°C. The LiFePO4 obtained has a high electrochemical capacity and good cycle ability. These results indicate that microwave processing is a promising method for preparing LiFePO4 cathode materials.
