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.
Scanning probes & battery research
As demand for electric vehicles, portable electronics, and green energy storage grow, so too will the demand for better batteries. To improve on current battery technologies, researchers must intimately understand battery components
One of the possibilities of characterizing intermediate species created during a redox process, is to couple a spectrometer with a potentiostat
What is EIS ?
Electrochemical Impedance spectroscopy (EIS) is a powerful tool enabling the study of processes that occur at the interface of the electrode.

As opposed to standard cycling techniques, High Precision Coulometry (HPC) measurements can provide a reliable estimation of battery lifetime quickly
No need to plan your future analysis… Go straight ahead
It is time to demystify a false truth. You really do not always need to add points in the record settings of BT-Lab® and EC-Lab® in order to obtain highly accurate measurements.
Freedom, flexibility and control with Modify on-the-Fly
No need to stop the experiment with EC-Lab®’s “modify-on-the-fly” functionality
Why 4-point measurements?
A potentiostat / galvanostat is an instrument that can control both the current and the voltage imposed to a cell. For this purpose, Bio-Logic instruments require at least 4 cables:
