Customer ServiceLithium-ion battery fires generate intense heat and considerable amounts of gas and smoke. Although the emission of toxic gases can be a larger threat than the heat, the knowledge of such emissions is limited.
The analysis reveals that the measured values are significantly influenced by the types of calorimeters and smoke gas analyzers used as well as by the type of thermal runaway trigger. This meta-analysis can serve as an important basis for any risk assessment of lithium-ion batteries. 1. Background
Our quantitative study of the emission gases from Li-ion battery fires covers a wide range of battery types. We found that commercial lithium-ion batteries can emit considerable amounts of HF during a fire and that the emission rates vary for different types of batteries and SOC levels.
The trapped smoke was measured for +/- 50 minutes with Fourier-transform infrared spectroscopy (FITR) and sampled with gas washing bottles. The experiments were primarily focused on the properties of smoke and not on the Li-ion batteries fire behaviour.
Smoke from Li-ion battery fires was collected in an airtight bag. Hydrogen fluoride (HF) concentrations in the bag were detected over time, showing a decrease to levels ranging between 8% to 50% of the initial concentration within 20 minutes.
The hydrogen content of the released gases can give rise to vapour cloud explosion risks which have the potential to cause significant damage. TT advocates a range of measures to mitigate the risks. A prudent starting point would be to perform a fire risk assessment, considering the specific hazards presented by lithium-ion batteries.
