Abstract In this paper, the carbon coating modification of lithium titanate was carried out by using glucose as the organic carbon source. The Li₄Ti₅O₁₂ @C composite was synthesized by hydrothermal method. The structure of the composite was characterized by XRD, SEM and TEM. The constant current charge and discharge test method and EIS were used to test the electrochemical performance of composite materials. The experimental results show that Li₄Ti₅O₁₂ particles are uniformly distributed and uniformly coated by amorphous carbon layer. Proper carbon content can effectively alleviate the Li₄Ti₅O₁₂ agglomeration. The first discharge specific capacity of the composite with 7.5% carbon content is 225 mAh/g at 0.1 A/g. After 200 cycles, the discharge specific capacity remains stable at 193 mAh/g, and the Coulomb efficiency is 99.9%. The composite shows excellent rate performance and cycle stability.
