Abstract:

The research progress of chromatography-mass Spectrometry technology in the field of lithium-ion batteries is reviewed. Lithium-ion batteries have been widely used in electric vehicles, energy storage, mobile phones, etc. based on their green, excellent performance and other advantages. As one of the core components of electric vehicles, the performance of lithium batteries largely determines the technical level of electric vehicles. The electrical performance, safety performance, and stability of lithium-ion batteries directly affect the operating state of electric vehicles. In order to further improve the performance of lithium-ion batteries, product generation analysis and mechanism analysis will be of a great importance during charging and discharging. And accurate product detection is one of the key factors to ensure the accuracy of the analysis results. In this article, the progress of lithium metal anode passivation technology was introduced from the following three aspects, including: ① the solid electrolyte mesophase (ie SEI membrane) composition and electrolyte degradation analysis using TOF-SIMS and LC-IT-TOF-MS; ② the SEI membrane composition and morphology of different forms of graphite using TOF-SIMS and other combined technology; ③ the gas production under the conditions of abuse of lithium batteries and gas evolution behaviors for several cathode materials in lithium-ion batteries using GC-MS technology.
