Abstract
This application relates to the field of lithium-ion batteries, and discloses a method for preparing a high-flowability lithium titanate material, a method for preparing a negative electrode sheet, and a method for preparing a lithium battery. This application mainly improves the integrity and flowability of lithium titanate particles by adding an additional low-temperature sintering step after air jet milling. Simultaneously, throughout the entire lithium titanate preparation process, the particle size of the material is controlled and optimized during ball milling, spray drying, and air jet milling, resulting in a significant improvement in the flowability and particle integrity of the lithium titanate material prepared by the entire process. This further enhances its battery performance as a negative electrode active material and solves the problem of difficult slurry preparation caused by the poor flowability of lithium titanate materials after conventional air jet milling.
