For the goal of improving the electrochemical performance of TiO2 anode material, TiO2/C/BP composite anode electrode material is prepared by ball grinding-ultrasonic-hydrothermal method.Cyclic discharge specific capacity, ratio performance, cyclic voltammetry curve and alternating-current impedance of the material are measured.Results show that the phase structure of TiO2 remains unchanged after doping with graphite and black phosphorus, and TiO2/C/BP composites have an improved particles dispersibility, a reduced alternating-current impedance and an enhanced electrical conductivity. Compared with pure TiO2, TiO2/C/BP composites generates a current density of 100 mA•g-1, its specific discharge capacity at the first cycle increases from 320 mAh•g-1 to 502 mAh•g-1, and that at the third cycle increases from 175 mAh•g-1 to 335 mAh•g-1.After 100 cycles, specific discharge capacity of pure TiO2 drops to 98 mAh•g-1, that of TiO2/C/BP still maintains at 255 mAh•g-1.TiO2/C/BP composites exhibit better discharge specific capacity retention rate and coulomb efficiency stability. © 2021, China National Chemical Information Center.
