The invention discloses a mesophase negative electrode material and a preparation method thereof. The method comprises the following steps: 1, uniformly mixing spherical natural graphite with raw mesophase carbon microspheres and a graphitization catalyst to obtain a mixture; 2, carrying out heating kneading on the mixture and a graphitization adhesive for 1-2h to obtain a kneaded material; 3, pressing to form a block in order to obtain a formed body of the kneaded material; 4, charring the formed body at 800-1500DEG C under the protection of an inert gas, and cooling to room temperature; and 5, carrying out catalytic graphitization high temperature treatment at 2800-3200DEG C. The preparation method can further improve the charge and discharge capacity and the charge and discharge efficiency of the mesophase negative electrode material and improve the cycle performance of the material.
