Intercalation/deintercalation rate-determining process

The potentiostatic current transient (PCT) technique has been known as the most popular method to understand lithium transport through an intercalation electrode, based on the assumption that lithium diffusion in the electrode is the rate-determining process of lithium intercalation/deintercalation [45]. By solving Eick s second equation for planar geometry with I.C. in Equation (5.28), impermeable B.C. in Equation (5.29), and potentiostatic B.C. 

The most frequent method for the analysis of CTs from intercalation electrodes is based on the grounds that lithium diffusion in the electrode is the rate-determining process in lithium intercalation/deintercalation. " This involves the following the system is so kinetically fast that the equilibrium concentration of lithium is quickly reached at the interface...
