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.
