Negative electrode material, production method thereof, battery, and terminal

A production method of a negative electrode material, comprising:

• mixing a carbon source precursor and a doping element source, and enabling the carbon source precursor and the doping element source to react at 100° C. to 180° C., to obtain a modified carbon source precursor;
• and
• performing low-temperature pre-carbonization processing on the obtained modified carbon source precursor in a protective atmosphere at 500° C. to 800° C., and then performing high-temperature carbonization processing on the obtained modified carbon source precursor at 900° C. to 1150° C., to obtain a doped carbon material after cooling, wherein the doped carbon material comprises a carbon-based matrix and doping elements doped in the carbon-based matrix, the doping elements comprise 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, and Ma and Mb represent two different types of doping elements.
