  "textContent": "A negative electrode material of the lithium-ion battery, a preparation method therefor and an application thereof, and a lithium-ion battery include the same are provided. The negative electrode material has a core-shell structure. The core has a silicon-containing material while the shell has an organic lithium salt and a porous carbon film, and at least part of lithium ion is intercalated in the porous carbon film. The negative electrode material is prepared by (1) mixing a silicon source and a carbon source, and then calcining the mixture; (2) mixing the calcined product obtained in the step (1) with the organic lithium salt; and (3) subjecting the materials obtained in the step (2) of mixing to vacuum freeze-drying.",
