Abstract
A comparison was made for Li+ chemical diffusion coefficients (D Li) in graphite as calculated by mathematical models of Li+ intercalation under constant potential into semirestricted and restricted kinetic systems with mobile phase boundary and into a single-phase system. Close D Li values were calculated by means of double-phase models. The double-phase model produces 6–7-fold D Li coefficient as compared to the values of the single-phase model.
