Electrochemical dilatometer

Electrochemical Dilatometer

The optimal test cells for the measurement of electrode strain (thickness change) in aprotic as well as aqueous electrolytes.

Watch your electrodes breathing

Our new electrochemical dilatometer is available in two versions, the ECD-3 and the ECD-3-nano. The two instruments mainly differ in the resolution and drift stability of the displacement sensor system that is attached to the electrochemical cell. The electrochemical cell is identical for both versions.

Working principle

The ECD-3 and ECD-3-nano electrochemical dilatometer measure the thickness change of a working electrode during the electrochemical cycle. The heart of the dilatometer is an electrochemical cell hermetically sealed against ambient atmosphere.

The 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.

Optionally, a reference electrode REF can be placed at the edge of the frit close to the working electrode.
