Oxidative Electrolyte Solvent Degradation in Lithium‐Ion Batteries: An In Situ Differential Electrochemical Mass Spectrometry Investigation

Open access
Imhof, Roman, Novák, Petr·1999·Journal of The Electrochemical Society

Abstract

Differential electrochemical mass spectrometry (DEMS) was used to study the electrochemical decomposition of organic carbonate electrolyte solutions at practical lithium metal oxide composite electrodes used in lithium‐ion batteries. For propylene carbonate (PC), evolution was detected at , and composite electrodes. The starting point of gas evolution was 4.2 V vs. at , whereas at and , evolution was observed only above 4.8 V vs. . In addition, various other volatile electrolyte decomposition products of PC were detected when using , , and carbon black electrodes. In ethylene carbonate/dimethylcarbonate, evolution was detected only at electrodes, again starting at about 4.2 V vs. . © 1999 The Electrochemical Society. All rights reserved.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
