Laurence M. Peter: Electrochemical impedance spectroscopy and related techniques: from basics to advanced applications from basics to advanced applications from basics to advanced applications

Electrochemical Impedance Spectroscopy (EIS) is one of the key techniques in the fields of chemistry, physics, and engineering for the in-situ characterization of electrochemical, electrical, and interfacial phenomena.EIS can be applied to both electrochemical and solid-state systems to study questions, ranging from quantifying the timescales of electrical and electrochemical phenomena, to determining local charge densities, to screening and identifying loss processes under relevant operating conditions.Fundamentally, EIS probes the interaction of a sample with a time-varying electric field, yielding information about how the sample stores and dissipates the energy, thereby enabling the parameterisation of underlying physical and chemical processes.EIS has found wide-spread application in the fields of energy storage and energy conversion, and while the application potential of EIS is perhaps clear for many researchers in these fields, as EIS equipment is affordable, requires no specialized infrastructure, and the measurements are comparatively easy to perform, anyone who has used EIS in their research knows that the learning curve is very steep.It is challenging to define relevant physical questions, to design robust experiments, and to interpret the EIS data in a physically meaningful way; the danger of producing endless semicircles modelled with complex nested circuits with no physical relevance is very high.As a result, there is significant demand for accessible literature on EIS with contemporary application examples for beginners to the technique.Laurence M. Peter, a highly regarded expert in EIS, expertly navigates the challenge of guiding the beginner towards EIS on complex electrochemical systems.
