Expert Knowledge for Modern Electrochemical Systems

Knowledge on EIS, Batteries, Fuel Cells and Electrolyzers

Electrochemical Impedance Spectroscopy (EIS) has become a key technology for the analysis and optimization of modern electrochemical systems. Whether used in laboratories, development environments or automated production lines, EIS provides highly sensitive, non-invasive insights into the behavior of batteries, fuel cells, electrolyzers and corrosion-critical materials.

With the Knowledge section, SIVONIC offers a central resource that consolidates definitions, background information, diagnostic methods and technical insights in a clear and accessible manner. The goal is to support researchers, developers and production engineers with reliable, application-relevant information on modern measurement and diagnostic techniques.

Glossary

The comprehensive SIVONIC glossary explains essential terms related to impedance spectroscopy, electrochemical energy converters and quality assurance. Each term is clearly structured and linked to practical application contexts.
The glossary is continuously expanded and serves as a solid reference for the daily use of EIS in research and industry.

Discover how SIVONIC's electrochemical impedance spectroscopy (EIS) is used in practice in our use cases. Using real-world examples from battery, fuel cell, and electrolysis applications, we show how our measurement technology helps to specifically improve the performance, quality, and service life of electrochemical systems. The use cases offer you a quick and clear introduction to the wide range of applications for modern EIS diagnostics.

In the sub-section “Testing Procedures & Standards”, you will find harmonized EU methods for electrochemical impedance spectroscopy, protocols for accelerated stress tests, standardized procedures for high- and low-temperature electrolysis, and regulatory frameworks such as the EU Battery Regulation 2023/1542. This content supports organizations in designing compliant test processes and interpreting EIS data according to recognized international standards.
