| Abstract: | Cylindrical and flat one-layer lithium-ion batteries, as well as symmetrical cells with like electrodes, are studied using electrochemical impedance spectroscopy. Equivalent circuit is suggested, its parameters found, and the activation energies estimated for different stages of the electrode process. |
