Özet

In this study, a simulation of an electrochemical impedance spectroscopy for lithium-ion batteries was proposed. The electrochemical process was developed from battery electrode kinetics and mass transfer of mobile Li+ ions through negative and positive electrodes and electrolyte. The phenomena used in this process were represented by an equivalent electrical circuit. A mathematical model was designed using the equivalent circuit and its elements which are in fact battery parameters. The parameter values were presented as compared with real experimental impedance result. The results showed that the simulation and process development were in good agreement with the experimental data.
