Electrochemical Impedance Spectroscopy

Electrochemical Impedance Spectroscopy (EIS) is a non-destructive analytical technique used to study the electrical properties of electrochemical systems. It involves the application of a small amplitude sinusoidal voltage to a system and measuring the resulting current response. By varying the frequency of the applied voltage, the impedance of the system can be determined. EIS is commonly used in the field of space and astronautical engineering to study the behavior of batteries, fuel cells, and other electrochemical systems used in spacecraft. It can provide information on the state of charge, state of health, and performance of these systems, which is critical for ensuring the reliability and safety of spacecraft during missions.
