Electrochemical Dilatometer ECD series

The ECD-3 is a research grade instrument dedicated to the measurement of charge-induced strain (expansion and shrinkage) of electrodes down to the sub-micrometer range. The ECD-3 is particularly developed for the investigation of Li-ion battery and other insertion-type electrodes. It may be used in organic as well as aqueous electrolyte solutions. The ECD-3 is the result of more than 10 years experience in this field. The heart of the ECD-3 is an electrochemical cell , which is hermetically tight against the ambient atmosphere. The two electrodes inside are separated by a stiff glass frit, which is fixed in position. The upper (working) electrode is sealed through a thin metal membrane, which transmits any charge-induced height change to the sensor/load uni on the top.

A high-resolution displacement transducer detects dimensional changes from ranging from 20 nanometers up to 500 micrometers during an experiments, which can take between a few seconds and many days. A simple weight serves to adjust the load on the working electrode. Its potential can either be controlled against the counter electrode (cell voltage control) or against an additional reference electrode.
