Summary: | The invention belongs to the technical field of sodium battery negative electrode materials, and particularly relates to a lipophilic carbon-phosphorus composite sodium battery negative electrode material and a preparation method thereof.The preparation method comprises the following steps that 1, pumpkin peel is soaked in a sodium carbonate solution to be soft and dried in a natural ventilation state, and dried pumpkin peel is obtained; (2) putting the dried pumpkin peel into a muffle furnace for carbonization to obtain a hard carbon material; (3) adding the hard carbon material into a hydrothermal kettle filled with a sodium dodecyl benzene sulfonate solution, heating, and then drying to obtain a material after hydrothermal reaction; (4) carrying out ball milling on the material subjected to the hydrothermal reaction and red phosphorus to obtain a mixed material; (5) putting the mixed material into a tubular furnace, heating in a nitrogen atmosphere, and naturally cooling after heating is completed; and (6) |
