Abstract: Embodiments of the present invention provide a negative electrode material, including a doped carbon material. The doped carbon material includes a carbon-based matrix and doping elements doped in the carbon-based matrix. The doping elements include at least two of B, N, O, P, S, and F. At least a part of the doping elements form C-Ma-Mb chemical bonds with the carbon-based matrix. Ma and Mb represent two different types of doping elements. The negative electrode material includes the doped carbon material, and the doping elements in the doped carbon material form the C-Ma-Mb chemical bonds with the carbon-based matrix. Therefore, the negative electrode material has excellent fast charging performance. Embodiments of the present invention further provide a production method of the negative electrode material, a battery including the negative electrode material, and a terminal.
