Introducing a High Voltage Test System for EIS up to 20kHz

Posted by gamry on November 6, 2020

The new LPI1010 for doing Electrochemical Impedance Spectroscopy (EIS) on an entire stack or battery pack

Announcing the launch of a new high voltage test system for impedance measurements offering advantages to researchers who wish to study electrodes and mechanisms in batteries, fuel cells, and electrolyzers.

Vehicle electrification is requiring changes in how batteries and fuel cells are tested. The need continues to require electrochemistry to develop better and more efficient storage and conversion devices. The new LPI1010 High Voltage EIS system consists of an Interface 1010E potentiostat, an LPI1010 and a load or power supply depending on the application. This new system will modulate the load or power supply while measuring the voltage response of the entire stack.

LPI1010 with Power Supply

The precision of a dynamic electrochemical measurement, such as EIS, is important. The LPI1010 performs a statistical analysis of the data at each frequency during acquisition. The data is accepted only after the precision criteria are met. The precision criteria can be adjusted by the user.

Currently the LPI010 system is 100V with a 1000V coming soon. There is an optional Multichannel Electrometer available for up to eight differential voltages measurements within fuel cell stacks or battery packs.
