| titleOfInvention | Graphene/carbon-coated lithium titanate composite material and preparation method thereof |
| abstract | The invention discloses a graphene/carbon-coated lithium titanate composite material and a preparation method thereof, wherein titanium dioxide and tris (hydroxymethyl) aminomethane are prepared into a dispersion liquid, dopamine hydrochloride is added to initiate polymerization of the dopamine hydrochloride, and a polydopamine coating layer is formed on the surface of the titanium dioxide; washing the product, dispersing the product in deionized water again, adding graphene oxide, and forming a stable compound by utilizing the electrostatic interaction between the graphene oxide and the polydopamine coating; and uniformly mixing the dried composite with a lithium source, and roasting at high temperature in an inert atmosphere to finally obtain the graphene/carbon-coated lithium titanate composite negative electrode material. The method is characterized in that a continuous conductive network is constructed, and the particle size control and uniform distribution of lithium titanate particles are realized. The lithium titanate phase purity of the composite cathode material prepared by the method is high, and the material conductivity is good, so that the composite cathode material has excellent rate performance and cycle stability. |
