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. A re-fitting kit is available to use the ECC-REF cell in two-electrode configuration, thus converting the ECC-REF into the ECC-STD test cell.

Cell parts that come into 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.

As member of the modular ECC test cell series, the ECC-REF electrochemical cell fits into the ECC-STAND docking station.

Features
