Electrochemical Dilatometer
The optimal test cells for the measurement of electrode expansion in aprotic as well as aqueous electrolytes.
The optimal test cells for the measurement of electrode expansion in aprotic as well as aqueous electrolytes.
Our electrochemical dilatometers are the perfect instruments for detecting thickness changes of the individual electrode or the full cell stack during the electrochemical cycle. The most powerful version offers a capacitive parallel plate sensor system with a resolution of better than 5 nanometers.
The working electrode (WE) and the counter electrode (CE) are separated by a stiff glass frit soaked with electrolyte. The WE is sealed by meansof 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 WE is being detected without interference from the CE.
