What is EIS ?
Electrochemical Impedance spectroscopy (EIS) is a powerful tool enabling the study of processes that occur at the interface of the electrode.
EIS and Battery Screening
Article describing how advanced EIS battery cyclers can play a multipurpose role in battery screening.
How to check and correct the time-variance of your system under EIS measurements
Are you running EIS experiments on a corroding electrode or on a charging or discharging battery and obtaining unusual or strange data at low frequencies? You should check that the change of your system does not affect your EIS measurements. Here are a few tools available in EC-Lab® to help you deal with such situations.
How to make reliable EIS measurements
To be considered reliable, EIS measurements must be performed on a system that is linear, in a steady-state and time-invariant. Quality Indicators are made available to users of EC-Lab® to ensure that the system fulfills these requirements.

An Introduction to Local Electrochemical Impedance Spectroscopy
PEIS or GEIS? That is the question.
Electrochemical Impedance Spectroscopy (EIS) measurements are generally performed under potentio control (PEIS) rather than under galvano control (GEIS). In most cases, the potentio and galvano modes are equivalent and give the same results, except in some cases when galvano mode is recommended, for example, when the system changes during the measurement…
Obtain high quality measurements…
This article gives some tips to improve the quality of measurements, from optimizing the setup or the connection interfaces, to the geometry of the cell itself.
