EIS Measurement for Large Battery Cells: Fundamentals and Accurate Methods

Advantages of rapid, non-destructive electrical impedance spectrometry

The growth of large or high-power lithium-ion batteries has made electrical impedance spectrometry (ESS) and uninterruptible power supply (UPS) systems increasingly common. It’s crucial to understand their performance and quality, and electrical impedance spectrometry (EIS) provides a solution for use in R&D, manufacturing, and quality assurance. This non-destructive and rapid method uses small AC signals to evaluate internal battery reactions. 

High-resolution EIS instruments are essential for low resistance measurements in large cells. Impedance meters, simple in design, make EIS measurements easy for anyone. Join us to learn more.
