  "textContent": "A method for structural and chemical regulation of anode carbon materials of rate-type sodium-ion battery and an application thereof utilize active gas to etch and dope a carbon material at a certain temperature. The etching reflects a reaction between the active gas and carbon atoms. This process is accompanied by the introduction of non-carbon heteroatoms, thereby obtaining anode carbon materials of sodium-ion battery. The method utilizes active gases for etching to construct rich porous structures, and the introduction of heteroatoms such as N, O, and S can regulate surface chemical properties of the carbon material. Through synergistic effects of the porous structure and surface chemistry (atomic doping), the carbon material achieves a high sodium storage capacity of 388.97 mAh g, and under the condition of a high current density of 1 A g, it exhibits an ultra-high specific capacity of about 340 mAh g, while also showing excellent cycling stability.",
