Abstract: A carbon-based anode material having a surface formed with slightly oxidized pores, includes by weight: 10-30 parts of clay minerals, 5-8 parts of chitosan, 0.1-1 part of a cationic polymer, 0.1-1 part of tris-1-(2-methylaziridinyl) phosphine oxide, 3-8 parts of a conductive agent, 3-8 parts of absolute ethyl alcohol, 1-3 parts of potassium oxalate, and 10-15 parts of a binder. According to the invention, the cationic polymer and the tris-1-(2-methylaziridinyl) phosphine oxide are added on the basis of the chitosan and the clay minerals, the cationic polymer contains polynuclear olation complex ions with a high positive electrovalence, thus being able to closely adhering to the surface of clay to form a three-dimensional net structure, so multiple slightly oxidized pores are formed in the surface of the obtained carbon-based material in a carbonization process, and the finally obtained carbon-based anode material has good charge-discharge performance and cycle performance.
