Abstract
The investigation technique differential electrochemical mass spectrometry (DEMS) combines cyclic voltammetry with mass spectrometry. DEMS measurements enables to detect online gaseous products formed by electrochemical reactions. A new, simplified experimental set-up is presented, which allows to expand this method to high concentrated electrolyte solutions. For inorganic electrolyte, elaborated for a rechargeable Li/LiCoO2 battery system, the usually DEMS cell is improved as compact thin-layer flow cell. Chlorine evolution - substantial for overcharge protection in this battery system - is examined at Ni and Au electrodes.
