The invention discloses a raw material composition capable of being used for preparing MCMB. The composition is a suspension formed by coal tar pitch extracts after dispersed on dimethicone, and the coal tar pitch extracts are insoluble substances obtained by coal tar pitch powder after dissolution and impurity removal by n-hexane or toluene. The preparation method of the raw material composition includes filling the coal tar pitch powder into a Soxhlet extractor, performing repeated extracting, dissolving and impurity removing to obtain the insoluble substances through n-hexane or toluene; and then drying and grinding, and subjecting the substances to ultrasonic dispersion on the dimethicone. The method for preparing the MCMB anode material through the raw material composition includes heating the raw material composition to subject the material to a thermal condensation reaction to form micron-sized spherulite; and then subjecting the solid-liquid mixed phase after the thermal condensation to centrifugation, n-hexane extraction, repeated scrubbing and drying sequentially to obtain the MCMB anode material. The material and the methods are simple in process steps, low in cost and capable of being used for preparing high-quality MCMB.
