Test cell for use with aqueous electrolytes

The ECC-Aqu electrochemical cell is dedicated to the characterization of aqueous battery and capacitor systems. The cell is equipped with a reference electrode assembly. Cell parts that come in contact with the electrolyte are made of gold and PEEK and can thus withstand all common aqueous electrolytes like sulphuric acid (up to 50% concentration) or potassium hydroxide. Other construction materials like platinum are optionally available.
