Abstract: 

The kinetics of electrodiffusion processes in the lithiated carbon electrodes was investigated. A small-signal pulse potentiostatic method is employed for the estimation of lithium-in-carbon diffusion rate. Dependence of lithium chemical diffusion coefficient on the lithium concentration was recorded in potential range from 0.01 to 1 V vs Li/Li+, the values between 0 5·10-10 and 1.5·10-9 cmVs were registered. Temperature influence on the diffusion process in the lithiated carbon electrodes was studied.
