Test cell for time-resolved gas analysis. For Li-air and conventional Li-ion chemistries.

Our test cell dedicated to the in-situ gas analysis in aprotic Li-air and conventional Li-ion systems.
The ECC-DEMS features a current collector with a spiral-shaped flow-field that is to be constantly purged with a gentle stream of inert gas. Gases evolved or consumed at the working electrode may be analysed through the composition change of the gas stream that is to be passed along the spiral-type flow field below the working electrode. The composition of the outgoing gas can be analyzed by e.g. mass spectrometry.
The ECC-DEMS cell provides almost perfect plug-flow of the purge gas being essential for quantitative time-resolved analysis. Pressure gradient between cell headroom and spiral-type flow field effectively prevents back-mixing and ensures best possible time resolution.
