The ECD-1 is a research grade instrument dedicated to the measurement o harge-induced strain (expansion and shrinkage) of electrodes down to th ub-micrometer range. The ECD-1 is particularly developed for th nvestigation of Li-ion battery and other insertion-type electrodes. It may b sed in organic as well as aqueous electrolyte solutions. The ECD-1 is th esult of more than 10 years experience in the field.
The heart of the ECD-1 is an electrochemical cell, hermetically tight agains mbient atmosphere. The two electrodes inside are separated by a stiff glas rit that is fixed in position. The upper (working) electrode is sealed by mean f a thin metal membrane, through which any charge-induced height change i ransmitted towards the sensor/load unit above.
