ECC-DEMS
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 to constantly purge a gentle stream of inert gas. Gases evolved or consumed at the working electrode may be analyzed 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 an almost perfect plug-flow of the purge gas, essential for quantitative time-resolved analysis. The pressure gradient between cell headroom and spiral-type flow field effectively prevents back-mixing and ensures the best possible time resolution.
