Abstract:

The thermal runaway of lithium-ion batteries releases a significant amount of gas, drawing considerable attention from researchers. Detecting and analyzing these gas products is a crucial aspect of studying thermal runaway in lithium-ion batteries. This review first introduces the reactions occurring at various stages of thermal runaway and identifies the sources of the main gas products. It then focuses on the current primary detection and analysis technologies for thermal runaway gas products from lithium-ion batteries, including gas sensors, Fourier transform infrared spectroscopy (FTIR), gas chromatography (GC), gas chromatography-mass spectrometry (GC-MS), Raman spectroscopy, ion chromatography (IC), composite gas analyzers, and combinations of these technologies. The review summarizes the practical applications of each technology, evaluates their limitations, suggests problem-solving methods, and discusses the advantages, disadvantages, development, and application of these technologies. Furthermore, the current research status on the detection results of thermal runaway gas products is elaborated and analyzed from five aspects: gas generation mechanism, gas composition and production, combustion and explosion hazards, toxicity, and monitoring and warning, providing valuable insights for the safe use and development of lithium-ion batteries. Finally, based on an analysis of the advantages of detection technologies and research on gas products, gas sensors, and GC-MS combined with gas sensors are recommended as the most suitable gas analysis technologies, offering guidance for selecting appropriate detection methods. The future optimization, development directions, and prospects of gas product detection and analysis technologies are discussed, providing a reference for the advancement of related technologies.
