abstract: Electrochemical impedance spectroscopy has become a mature and well understood technique. It is now possible to acquire, validate, and quantitatively interpret the experimental impedances. This chapter has been addressed to understanding the fundamental processes of diffusion and faradaic reaction at electrodes. However, the most difficult problem in EIS is modeling the electrode processes, which is where most of the problems and errors arise. There is an almost infinite variety of different reactions and interfaces that can be studied (corrosion, coatings, conducting polymers, batteries and fuel cells, semiconductors, electrocatalytic reactions, chemical reactions coupled with faradaic processes, etc. and the main effort is now being applied to understanding and analyzing these processes. These applications will be the subject of a second review in a forthcoming volume in this series.

abstract: Electrochemical techniques have been widely employed to detect and/or quantify molecules of medical, environmental and industrial interests. Among traditional techniques such as potentiometry, amperometry and conductometry, the Electrochemical Impedance Spectroscopy (EIS) has gained great attention as an analytical tool for a broad range of analytes, mainly because it can be performed as a non destructive method and it enables in situ measurements.1,2 Moreover, EIS exempt the use of special reagents, which makes it suitable for label free applications, which significantly diminishes its cost in relation to other techniques and makes it easier to perform.3 In common, all the electrochemical sensors consist on relating a measurable output electrical signal to the changes in the structure (usually the surface) of an electrode because of the recognition of a target analyte. The in depth understanding of the mechanisms and fundaments involving the sensing phenomena is a challenge in electroanalytical techniques and can lead to the improvement of the main desirable characteristics of a sensor: the selectivity, stability and sensibility.4 In this sense, this minireview presents the main aspects regarding the EIS as a technique for application in sensors based on its two categories of performance: the Faradaic and non faradaic EIS.

abstract: We report an extraction reconstruction strategy for obtaining a novel voltammogram for a specific electrochemical process. While a conventional voltammogram is obtained from potentiodynamic currents, our voltammogram is obtained from a large body of potentiodynamic electrochemical impedance spectra by taking advantage of their highly resolvable power. As a proof of concept, construction of a mass transfer admittance voltammogram (MTAV) is demonstrated, which is made up of purely mass transfer admittances plotted vs. potential, excluding effects from other interfering electrochemical components. We also compare the MTAV with the AC voltammogram to show its enhanced accuracy and apply the novel voltammetry to clearly determine the number of electrons transferred and diffusion coefficients, which may vary depending on experimental conditions, for a complex electrochemical reaction.

abstract: As research on secondary batteries becomes important, interest in analytical methods to examine the condition of secondary batteries is also increasing. Among these methods, the electrochemical impedance spectroscopy (EIS) method is one of the most attractive diagnostic techniques due to its convenience, quickness, accuracy, and low cost. However, since the obtained spectra are complicated signals representing several impedance elements, it is necessary to understand the whole electrochemical environment for a meaningful analysis. Based on the understanding of the whole system, the circuit elements constituting the cell can be obtained through construction of a physically sound circuit model. Therefore, this mini review will explain how to construct a physically sound circuit model according to the characteristics of the battery cell system and then introduce the relationship between the obtained resistances of the bulk (Rb) charge transfer reaction (Rct) interface layer (RSEI) diffusion process (W) and battery characteristics, such as the state of charge (SOC) temperature, and state of health (SOH)

abstract: A critical review of electrochemical impedance techniques in corrosion research is presented. Electrochemical impedance spectroscopy (EIS) is a powerful in situ technique used in corrosion research owing to its promise in providing information on various fundamental/complex electrochemistry processes that occur at the metal/electrolyte interface. EIS has played a pivotal role in defining new information in corrosion research and materials characterization. Using EIS in combination with new surface analytical and imaging tools, it is now possible to characterize the structure, growth kinetics and electronic properties of passive oxide films at the nanoscale level. Successful use of EIS as a corrosion monitoring tool has been demonstrated in many recent studies. The power of EIS in characterizing a wide range of electrochemical corrosion systems and use of various new impedance techniques, including those of combined electrochemical, microscopic and mechanical techniques for studying physico electrochemical systems are briefly described. The purpose of this paper is to critically review the recent advances of EIS in unraveling the response mechanisms of electrochemical nature of corrosion. More importantly, the various advantages offered by EIS over other electrochemical techniques are discussed. The paper also provides a brief review of EIS, with emphasis on those developments that have propelled the impedance technique into the forefront of corrosion research in India.

abstract: Electrochemical impedance spectroscopy (EIS) is a nondestructive technique often used to understand the interfacial behavior in electrochemical systems. The ability of the technique to segregate various processes, i.e. ohmic conduction, charge transfer interfacial charging, mass transfer etc, makes it an elegant technique for electrochemical systems. Its applicability to lithium ion cells is further enhanced by the fact that surface films cover both the electrodes and especially the carbon anode. This paper describes the EIS response of individual electrodes in the lithium. ion cells under a variety of experimental conditions, i.e. temperature, high temperature storage and cycling.
