The present invention relates to a negative electrode material for a secondary battery, a manufacturing method thereof, and a secondary battery including the same as a negative electrode. The negative electrode material for a secondary battery of the present invention is characterized by including a negative electrode active material and a fluorine compound. According to the present invention, by stabilizing the surface of the negative electrode active material to reduce the effect of the organic electrolyte solution decomposition reaction, which is the main cause of irreversible capacity, and to reduce the influence on the acid generated by the oxidation of the electrolyte during charge / discharge to improve the efficiency and cycle characteristics There are advantages to it. |
