Lithium-ion batteries are combustible and hazardous, with the potential of dangerous and explosive thermal runaway – which can not only have devastating consequences for the environment and property but can threaten human life. Therefore, it is important to understand the first signs of a possible disaster – off-gassing.
Gases generated from lithium batteries are detrimental to their electrochemical performances, especially under the unguarded runaway conditions, which tend to contribute the sudden gases accumulation (including flammable gases), resulting in safety issues such as explosion and combustion. The comprehensive understanding of battery gas evolution …

The toxicity of gases given off from any given lithium-ion battery differ from that of a typical fire and can themselves vary but all remain either poisonous or combustible, or both. They can feature high percentages of hydrogen, and compounds of hydrogen, including hydrogen fluoride, hydrogen chloride and hydrogen cyanide, as well as carbon monoxide, sulphur dioxide …
Gases generated from lithium batteries are detrimental to their electrochemical performances, especially under the unguarded runaway conditions, which tend to contribute the sudden gases accumulation (including flammable gases), resulting in safety issues such as explosion and combustion. The comprehensive understanding of battery gas evolution mechanism under …
Before the occurrence of thermal runaway, when the temperature of lithium batteries increases, a large amount of flammable gas is released, forming a bulge within the battery. Battery safety devices such as temperature sensors and gas sensors are employed to monitor and warn about hazards and to prevent further escalation of battery failures. These …
Safety of lithium-based batteries has attracted much media and legal attention. Any energy storage device carries a risk, as demonstrated in the 1800s when steam engines exploded and people got hurt. Carrying highly flammable …
When a large amount of electrolyte evaporates when batteries are heated, this gas may not ignite immediately when released but may accumulate and result in gas explosions at later stages (Larsson et al., 2017). …
Lithium batteries are both flammable materials and sources of ignition. Once collision, extrusion, overcharge, short circuit, etc. occur, it can easily cause fires, explosions and other safety accidents, resulting in …
Lithium-based batteries have the potential to undergo thermal runaway (TR), during which mixtures of gases are released. The purpose of this study was to assess the explosibility of the gaseous emission from LIBs of an NMC-based cathode during thermal runaway. In the current project, a series of pouch lithium-based battery cells was exposed to …
