EnergyLab XM Potentiostat Galvanostat


EnergyLab XM is an application specific XM instrument designed for research of batteries, fuel cells, and supercapacitors. EnergyLab XM’s extreme sensitivity is used for advanced testing of lithium ion batteries and alkaline batteries. This includes research in half-cell configurations and next generation low impedance cells in the sub 100 μΩ range as well as popular battery types such as 2032 coin cell testing and 18650 cell testing.

EnergyLab XM includes a reference grade potentiostat galvanostat, frequency response analyzer (FRA), auxiliary voltage channels and 2A booster. These features provide accuracy to the most common tests for impedance and battery capacity (charge discharge) to measure rated capacity (mA h) or energy (watt hours) that a battery can deliver.

High current may be needed for battery testing, to either fully charge or fully discharge the battery cell at high discharge rate or measure low impedance. External power boosters up to 100 A can be connected to the EnergyLab XM. Our boosters are automatically controlled for fully integrated tests.

All modes -- poteniotstat, galvanostat...boosted and non -- make use of Solartron Analytical’s unique auxiliary channel capability. These auxiliary channels can measure nominal voltage across the battery terminals of a single cell in a stack or at the cell level across the anodes, cathodes, separators.  Simultaneous coordinated measurements of DC and impedance can identify the mode of battery failure and predict battery life.

EnergyLab XM’s impedance accuracy contour plot highlights Solartron’s best in class measurement performance.
