The application of Electrochemical Impedance Spectroscopy to the study of surface electrode processes is reviewed. The impedance expressions and the physical meaning of the parameters included in them are shown for three surface processes: adsorption kinetics, diffusion towards partially blocked electrodes and surface confined redox reactions. The models are applied to selected examples, showing the capability of Electrochemical Impedance Spectroscopy to obtain fundamental kinetic information of these processes.

ABSTRACTIt is of great significance to understand and monitor the condition of the commercial batteries in EVs/HEVs and stationary applications under their real working situations. Electrochemical impedance spectroscopy (EIS) has been proved to be a powerful technique for investigating the kinetics and redox reactions at the interfaces, as well as the diffusion behavior in the bulks of every electrochemical systems. Focusing on tracing the temperature of the commercial batteries during the EIS tests at different stages in a well-designed four-week driving simulation, the value of temperature profile during the EIS test as an enhanced indicator to help analyzing the formation of the passivation layers, electrolyte impedance development as well as lithium plating on the anode through EIS analysis have been found.

The electrode processes governing response behavior of a solid electrolyte CO2 sensor have been studied using electrochemical impedance spectroscopy on symmetric cells exposed to various temperatures and gas compositions. It was shown that the electrochemical processes leading to potential formation at the Au/Na2CO3 electrode can be described by adapting models commonly used in the field of molten carbonate fuel cells.

Lithium Sulfur

Electrochemical impedance spectroscopy is used to study novel cathode materials for lithium-sulfur batteries, based on commercial carbon and titania. Coin cells with Li anode are investigated at various stages of galvanostatic cycling. For comparison, also symmetrical coin cells with a pair of positive (S/C/TiO2) or negative (Li) electrodes are studied. In addition to the application of titania as a barrier material impeding the polysulfide diffusion in the electrolyte solution, the inherent Li-insertion activity of TiO2 (anatase) and its contribution to the sulfur redox reactions is discussed.
