The galvanostatic intermittent titration technique was employed to investigate the diffusion processes of lithium in carbon materials. The results showed that the diffusion coefficients of lithium in the graphite region of carbon materials were all similar, while in the non-graphitic region they vary with the structure of the carbon materials.
