The present invention relates to a manufacturing method of a carbon negative electrode material, comprising: a step of performing oxidation treatment to pitch, and a step of carbonizing the oxidated pitch in an inert gas. A manufacturing method of the pitch comprises: a step of performing heat treatment to the petrochemical coproduct under high temperature and high pressure, and a step of adding a high-acidity catalyst material during the heat treatment. Compared with the prior art, the present invention is characterized in that: the material used for improving yield and performance is added in the high temperature and high pressure heat treatment; an intermediate additive is used as the catalyst during the manufacture of the pitch, thereby raising the yield; in addition, the efficiency and the capacity of a battery manufactured by utilizing the pitch also can be raised.
