Setup Design and Data Evaluation for DEMS in Sodium Ion Batteries, Demonstrated on a Mn-Rich Cathode Material

Analysis of side reactions in Na-ion batteries: This study describes the development of a differential electrochemical mass spectrometry setup with reference electrode. The data is evaluated using the full MS-spectra for a multiple concentration determination algorithm, to quantify the gas release. The setup is demonstrated for P2-Na0.67Mn3/4Ni1/4O2 cathodes with two electrolytes, NaPF6 in propylene carbonate and in diglyme. DEMS
