  "textContent": "The present disclosure relates to the technical field of batteries, and in particular, to a modified lithium ion negative electrode material, and preparation therefor and use thereof. The preparation method includes the following steps: dropwise adding a mixed solution of a titanium source and a lithium source into a mixed solution of an iron salt and an organic acid, adjusting the pH to 5.0-7.0, and stirring to obtain a wet gel; drying and crushing the wet gel, and then calcinating to obtain a LiFeTiOcomposite oxide; and reducing the LiFeTiOcomposite oxide to obtain the modified lithium ion negative electrode material. In the present disclosure, a spinel modified negative electrode material lithium iron titanium oxide is synthesized by using a citric acid sol-gel method, thereby not only greatly improving the charging and discharging capacity thereof, but also improving the large-current charging and discharging capability thereof.",
