Advanced test cell for the measurement of the electrode expansion in the nanometer range.
The ECD-4-nano takes dilatometry measurements to the next level
The ECD-4-nano is a high-resolution electrochemical dilatometer. The most powerful version offers a capacitive parallel plate sensor system with a resolution of better than 5 nanometers. This makes the ECD-4-nano the perfect instrument for detecting thickness changes of the individual electrode or the full cell stack during the electrochemical cycle.
The ECD-4-nano‘s completely redesigned test cell features a corrosion-resistant cell bottom and a new One-Seal concept that significantly improves tightness over previous ECD-3 models. This enables stable long-term operation as well as the use of a wide range of electrolytes.
To further improve workflow and handling, we have now integrated the ECD-4-nano into the PAT system. The dilatometer can be inserted directly into a PAT-Tester-x or a docking station such as the PAT-Clamp-1. This allows a space-saving and fast setup of the instrument. Needless to say, the integrated PAT-Button also ensures automatic recognition of the test cell in our EL-Software measurement software.

Sample Setup

Working principle of the ECD-4-nano (3-electrode setup)
he working electrode (WE) and the counter electrode (CE) are separated by a stiff glass frit soaked with electrolyte. The upper WE is sealed by means of a flexible metal membrane, through which any charge-induced thickness change is transmitted towards the sensor/load unit attached on top. The fixation of the glass frit ensures that only the thickness change of the working electrode is being detected without interference from the CE.
