ECC-Std

Electrochemical Test Cell

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 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-STD electrochemical cell fits into the ECC-STAND docking station (Accessories).
