NOVELTY - Electrode material with multistage aperture distribution structure comprises basic structural units which are connected through carbon skeleton. The carbon skeleton is prepared by carbonization of a carbon-containing organic substance as a binder, and the electrode material particle diameter is 0.2-20 mu m. The electrode material is prepared by mixing basic structural unit raw material and carbon-containing organic material as a binder and carbonizing at 500-1200 degrees C. The mass ratio of basic structural unit and binder is 1:5-20:1.    USE - The electrode material is useful as cathode material in lithium air battery or lithium thionyl chloride battery (claimed).    ADVANTAGE - The electrode material improves mass transfer capacity of battery.    DETAILED DESCRIPTION - Electrode material with multistage aperture distribution structure comprises basic structural units which are connected through carbon skeleton. The carbon skeleton is prepared by carbonization of a carbon-containing organic substance as a binder, and the electrode material particle diameter is 0.2-20 mu m.
