The effect of cycling degradation on the kinetic characteristics of graphitized carbon electroactive material is investigated using laminated Li-ion cells incorporating a reference electrode. By carrying out electrochemical impedance spectroscopy (EIS) measurements at different state of charges and temperatures and obtaining dQ/dE vs. E curves, the pre-exponential factor and activation energy of Li-ion insertion/deinsertion reactions are analyzed as a function of anode potential. The kinetic behavior of charge transfer, Li-ion conduction and Li-ion solvation/desolvation reactions for Li-ion cells without degradation and after cycling degradation are investigated. Structural changes in the crystal structure of graphitized carbon originated from cycling degradation affect the charge transfer reactions, while irregular growing of the SEI affected the Li-ion conduction and Li-ion solvation/desolvation processes.
