ECC-Combi

The ECC-Combi used as ECC-Std
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.

Cell parts that come into contact with the electrolyte are made of stainles steel and PEEK and can thus withstand all common aprotic organic electrolytes used in lithium-ion battery and aprotic supercapacitor technology. Current collectors are also available in many other metals like 316L (1.4404), gold and tantalum.

The ECC-Combi used as ECC-Ref
Electrochemical test cell with reference electrode

The ECC-Ref electrochemical cell is dedicated to the characterization of aprotic battery and capacitor systems in three-electrode configuration. A typical application is the characterization of a full lithium-ion battery (e.g. graphite anode and lithium metal oxide cathode) with a lithium metal reference.

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. Current collectors are also available in many other metals like 316L (1.4404), gold and tantalum.
