In-situ Electrochemical Mass Spectrometer (Battery DEMS)

Introduction to Differential Electrochemical Mass Spectrometry (DEMS)

Mass spectrometry is a powerful instrument for identifying substance compositions and can be used for gas analysis. Its advantages lie in its ability to analyze a wide range of substances, from the smallest hydrogen molecules to large organic vapors with molecular weights in the hundreds. It is a versatile gas analyzer with low detection limits, high sensitivity, wide linear range, and minimal gas consumption. Additionally, it allows for isotope labeling and finds broad applications in gas analysis for various types of batteries.

In-situ electrochemical mass spectrometry, also known as online electrochemical mass spectrometry, differential electrochemical mass spectrometry (DEMS), or online electrochemical mass spectrometry (OLEMS), is particularly useful for in-situ gas analysis during the charge and discharge processes of energy storage devices such as lithium-ion batteries. For gas-consuming battery types, like air batteries, it enables quantitative analysis of gas consumption. This technique provides real-time insights into the gas generation or consumption during different stages of battery operation, allowing for the determination of gas distribution patterns as voltage varies. As such, it is an essential analytical tool for investigating battery electrochemical reaction mechanisms, rapidly screening electrode materials, and evaluating electrolyte decomposition, among other crucial applications.
