Mass Spectrometry in Lithium-Ion Battery Testing
As a high energy density and long-life energy storage device, lithium-ion batteries are widely used in various electronic products, electric vehicles and energy storage systems. However, the performance of lithium-ion batteries decreases with the increase of usage time, and their safety issues become more and more obvious. Therefore, it is of great significance to study the composition and internal reaction processes of lithium-ion batteries to improve their performance and ensure their safety. Mass spectrometry, as a highly accurate and sensitive analytical tool, can play an important role in lithium-ion battery testing. In recent years, with the development of technology and the emergence of time of flight mass spectrometry (time of
