NOVELTY - A preparation of a functional composite carbon material doped with transition metal atoms, involves (S01) adding transition metal acetate and 2,2'-bipyridine into the flask according to the molar ratio of 1:3, and then adding an appropriate amount of ethanol and stirring, (S02) adding a certain amount of carbon material to the solution after stirring in S01, and continuing to heat after stirring to evaporate ethanol to obtain a black solid, (S03) putting the black solid obtained by (S02) into a vacuum drying oven and drying to obtain a black substance, (S04) transferring the black substance obtained in (S03) to a mortar and grinding to fine powder, and (S05) transferring the grinding product of (S04) to a quartz boat, putting it into a tube furnace, and heating and carbonizing in an argon atmosphere. USE - Preparation of a functional composite carbon material doped with transition metal atoms used in lithium-sulfur battery (all claimed) used in automobile. ADVANTAGE - The preparation method can reduce the synthesis cost of the metal diatomic material, and at the same time improve the catalytic activity of the carbon material by doping with metal elements.
