A novel synthetic method of microwave processing to prepare Li₂FeSiO₄ cathode materials is adopted. The Li₂FeSiO₄ cathode material is prepared by mechanical ball-milling and subsequent microwave processing. Olivin-type Li₂FeSiO₄ sample with uniform and fine particle sizes is successfully and fast synthesized by microwave heating at 700℃ in 12 min. And the obtained Li₂FeSiO₄ materials show better electrochemical performance and microstructure than those of Li₂FeSiO₄ sample by the conventional solidstate reaction.
