Abstract
The present disclosure discloses a method for preparing carbon-coated lithium titanate, and provides a method for preparing a carbon-coated lithium titanate anode material for a lithium battery. The method prepares a lithium titanate precursor first, then coats a polymer on the surface of the precursor through emulsion polymerization, and finally performs sintering, and obtaining a carbon-coated lithium titanate material. The present disclosure obtains a carbon source of the polymer through the emulsion polymerization. The carbon source is coated on the surface of lithium titanate uniformly and compactly with a better coating effect than a common mechanical mixing method. The polymer is coated while agglomeration of a lithium titanate crystal is prevented during the emulsion polymerization process, and an obtained product has a small particle size and a uniform size. The carbon-coated lithium titanate prepared by the present disclosure has excellent cycling performance during charging and discharging at a high rate.
