Electrochemical Impedance Spectroscopy (EIS) is a non-destructive, rapid, and efficient electrochemical testing method. It separates the processes involved in electrochemical reactions in the frequency domain based on the speed of the electrochemical system’s response to the excitation signal. The analysis of EIS is a complex task. A commonly used method is the equivalent circuit model, … Read more
To ask which technology in electrochemical testing is the most hair-pulling, I would say it’s EIS (Electrochemical Impedance Spectroscopy), and I think hardly anyone would disagree. There is “poetry” to prove: Measuring impedance is tough, Equivalent circuits are hard to guess; If you ask if performance improves? We’re happy if the arc shrinks! Although the … Read more
First Author:Ruizhuo Zhang Corresponding Authors:Torsten Brezesinski, Jürgen Janek Affiliation: Karlsruhe Institute of Technology, Germany [Achievement Overview] The commonly used dual-electrode (2E) configuration in solid-state batteries (SSBs) is often insufficient to resolve the electrochemical processes of the anode/cathode. Here, Professors Torsten Brezesinski and Jürgen Janek from the Karlsruhe Institute of Technology introduce a three-electrode (3E) battery … Read more
