    摘要： The present invention relates to the field of electrode materials, and more specifically, to a carbon-deposited alkali metal oxyanion electrode material as well as to a process for preparing same. More particularly, the process for preparing the carbon-deposited alkali metal oxyanion electrode material comprises a dry milling step of precursors of the alkali metal oxyanion electrode material at an energy sufficient to cause the precursors to agglomerate into strong agglomerates, and a heating step comprising pyrolysis of an organic source to obtain the carbon-deposited alkali metal oxyanion electrode material.
