| titleOfInvention | Controllable synthesis method and application of lithium titanate micron-sized spherical secondary structure |
| abstract | The invention discloses a controllable synthesis method of a lithium titanate micron-sized spherical secondary structure, which comprises the steps of dissolving a titanium source and a surfactant in water, performing ultrasonic dispersion to obtain a titanium source dispersion liquid, adding a lithium source, performing further ultrasonic dispersion, adding a buffering agent, and adjusting the pH value to be>And (3) uniformly stirring at a constant temperature of 11 ℃ to 30 ℃ to obtain a mixed solution, reacting the mixed solution at 100 ℃ to 180 ℃ for 4-24 h, washing and drying the obtained product to obtain a lithium titanate precursor secondary structure, and finally calcining the lithium titanate precursor secondary structure at 400 ℃ to 1000 ℃ for 6-48 h in an inert atmosphere to obtain the lithium titanate precursor. The preparation method provided by the invention regulates the concentration of the raw material through the surfactant, and simultaneously regulates the pH of the reaction solution by using the buffer solvent, so that the controllability of the size of the lithium titanate micron-sized spherical secondary structure is realized, the product lithium titanate micron-sized spherical secondary structure has uniform particle size and stable structure when the pH and the raw material concentration are fixed, the obtained lithium titanate micron-sized spherical secondary structure is used as a high-specific volume capacity electrode material to be applied to a lithium ion battery, and the specific volume capacity can reach 120 ion-doped 232mAh/cm 3 And has good cycle stability. |
