摘　　要：The potentiostatic intermittent titration technique(PITT) method was used to determine lithium ion diffusion coefficients in graphitized carbon fiber anode material as function of potentials. The plot of lg D vs E shows that the value of lithium ion coefficients in graphitized carbon fiber anode material has three minima, the least value obtained is 1 9×10 -13 cm 2/s.The potentiostatic intermittent titration technique(PITT) method was used to determine lithium ion diffusion coefficients in graphitized carbon fiber anode material as function of potentials.
