Ponchaut et al. (2015) quantified the vent gas composition, heat generation, and overpressure resulting from the combustion of vent gases released during a thermal runaway of a soft-pack pouch cell. Fernandesa et al. (2018) identified and quantified gases emitted during abuse tests by overcharge of a commercial Li-ion battery.
Several studies have experimentally characterized battery gas composition released during thermal runaway. These studies are summarized in Table 1 . In many of these studies, lithium-ion cells are failed within an enclosed chamber from which the evolved gases are extracted and analyzed.
The gas composition was significantly dependent on the battery chemistry as two NMC cells produced similar gas components. The LFP cell produced the highest levels of H 2, C 2 H 2, C 2 H 4, and C 2 H 6, but lowest for CO. The NMC cell produced the highest levels of CO and CH 4, but the lowest levels of C 2 H 4 and C 2 H 6.
Permanent gases, such as nitrogen, oxygen, carbon monoxide, and argon, were detected, as well as gases produced by the lithium battery, such as methane, ethane, ethylene, propane, propylene, acetylene, butane, and isobutane. Additionally, byproducts of lithium battery thermal runaway were also detected
is the gas–solid ratio of the battery, defined as the ratio of the gas mass to particle mass produced during the TR of the battery. The calculation is based on the initial weight and residual weight of the battery as well as the mass of particulate matter ( ) collected after the test.
In mid- and large-scale, multi-cell battery installations, e.g. electric vehicle traction batteries and stationary energy storage systems, the TR can propagate from cell to cell within the battery, thus aggravating the situation. Gassing in Li-ion cells is researched extensively due to the flammability and toxicity of the species formed.
We found that the amount of released gases was up to 102 ± 4 L, with a clear dependence on the battery capacity. This study showed that the concentration of gaseous emissions such as carbon monoxide (CO), methane (CH4), ethylene (C2H4), ethane (C2H6), and hydrogen cyanide (HCN) increased with higher cell capacity.
