The invention discloses a low-cost artificial graphite negative electrode material. The low-cost artificial graphite negative electrode material is prepared from the following raw materials in parts by weight: 25 to 29 parts of asphalt powder, 22 to 26 parts of sodium hydroxide, 8 to 12 parts of naphthenic acid, 10 to 14 parts of sodium nitrite, 5 to 9 parts of hydrogen peroxide, 6 to 10 parts ofphenol, 4 to 8 parts of polyphenylacetylene and 7 to 11 parts of trichloroethylene. The low-cost artificial graphite negative electrode material has the advantages that the practicability is high, a preparation process is simplified, the production cost is reduced and the service life is prolonged.
