| titleOfInvention | Modified N, P co-doped lithium titanate negative electrode material and preparation method thereof |
| abstract | The invention provides a modified N, P co-doped lithium titanate negative electrode material and a preparation method thereof, and particularly relates to the technical field of negative electrode materials of lithium ion batteries, namely, LiOH & H 2 And mixing O and anatase to obtain a precursor. Putting the precursor and anhydrous sodium hypophosphite into a tube furnace, and introducing NH 3 And N 2 And heating the mixed gas to 800 ℃ to obtain the nitrogen and phosphorus co-doped lithium titanate material. Adding petroleum asphalt, inorganic matters, an organic solvent and nitrogen and phosphorus co-doped lithium titanate particles into a 100mL round-bottom flask, uniformly mixing, and removing the organic solvent by rotary evaporation. The mixture after removal of the organic solvent is transferred into a tube furnace and passed through H 2 And Ar mixed gas is heated to 800-850 ℃ and is kept at the constant temperature for 1h, and then the temperature is reduced to 400 ℃ and is kept at the constant temperature for 1 h. After the temperature is reduced to room temperature, removing inorganic matters in the mixture by using 1mol/L hydrochloric acid, centrifugally washing, and then drying in vacuum for 12 hours to obtain the product. The invention can ensure that the whole composite material is uniformly and compactly dispersed, thereby maintaining the stability and high conductivity of the electrode structure. |
