  "textContent": "The invention discloses a preparation method of an anode material for lithium-ion batteries, comprising: dispersing tetrabutyl titanate in glycerol solvent and adding hexadecyl trimethyl ammonium bromide solution, adding tetramethylammonium hydroxide to adjust Ph; then adding ammonium fluoride solution, heating at 150-200° C. for 1˜6h, the product was centrifuged, washed, and dried in vacuum to obtain titanium/nitrogen/fluorine-doped porous titanium dioxide; preparing the titanium/nitrogen/fluorine-doped porous titanium dioxide organic solution, and then adding lithium salt solution, then adding graphite, mixing uniformly, and spray drying to obtain porous lithium titanate-coated graphite composites; taking porous lithium titanate-coated graphite composites and ammonium fluoride, placing them in a tube furnace, heating them under the protection of argon, and then heating them up to carbonization. The invention can improve the first-time efficiency of graphite composites and their power performance.",
