The Li2ZnTi3O8@polyaniline (LZTO@PANI) composite materials were prepared by sol?gel and chemical oxidation polymerization methods using tetrabutyl titanate, zinc acetate, lithium acetate and aniline as raw materials. The materials were characterized and analyzed by X?ray diffraction (XRD), infrared spectroscopy (IR), scanning electron microscope (SEM) transmission electron microscope (TEM) and electrochemical testing. The results show that the polyaniline in the composite material has an amorphous structure and no impurities are introduced. When the coating amount of polyaniline is 5.3%, the discharge specific capacity is 330.0 (mA·h)/g at 0.1 A/g. In addition, after 100 cycles, the specific discharge capacity is 281.3 (mA·h)/g.
