Electrochemical test cell for two-electrode battery testing

The ECC-Std electrochemical cell is dedicated to the characterization of aprotic battery and capacitor systems in two-electrode configuration. The most typical application is the characterization of a lithium-ion battery electrode (anode or cathode) against a lithium metal counter electrode. A re-fitting kit is available to use the ECC-Std cell in combination with a reference electrode, thereby converting the ECC-Std into the ECC-Ref test cell.
Cell parts that come in contact with the electrolyte are made of stainless steel and PEEK and can thus withstand all common aprotic organic electrolytes used in lithium-ion battery and aprotic supercapacitor technology.

ECC-Std overview


High precision 18 mm diameter sandwich geometry with <0.1 mm electrode concentricity

Adjustable, reproducible and homogeneous mechanical pressure on electrodes

Reliable low leakage sealing with PE washers

Easy and reliable electrolyte filling upon assembly

Fast assembly and dismantling and easy cleaning of cell components

Electrodes are easily accessible for post-mortem analysis

Reusable cell components except for PE sealing

Materials in media contact are stainless steel 1.4404 and PEEK

Small and defined electrolyte volume down to 0.05 cm³ due to minimized dead volume

Materials in media contact are stainless steel and PEEK
