Explosion is the most extreme case of thermal runaway of lithium-ion (Li-ion) batteries. In this study, explosion dynamics of large-format Li-ion cells are investigated experimentally and numerically. Overcharge-to-explosion tests are conducted on 40 Ah Li-ion cells with Li[Ni 0.8 Co 0.1 Mn 0.1]O 2 cathode. Based on the explosion physics

In August 2023, the thermal runaway of an EV battery caused a severe explosion in a detached garage that knocked down masonry walls, destroyed adjacent car bays and damaged nearby homes [8].
Lithium-ion batteries power modern electric vehicles, but when exposed to water, they pose significant safety risks. This article explains how submerging these batteries can lead to short circuits, thermal runaway, chemical fires, and explosions, and provides tips for safe handling and storage.
Saft is offering a number of solutions for use in explosive atmospheres; either as a partially tested component or certified equipment. Saft batteries'' long lifetime is also an advantage to avoid replacement in remote or hard-to-reach locations.
These problems have to be verified in several applications and in particular, when Lithium-ion battery are used in Explosive Atmosphere. The goal of this Paper is the evaluation of the most safety type of Lithium technology in order to minimize the possible ignition source in the environment with presence of Explosive Atmosphere.
According to the characteristic of parameters, the sensitivity and severity were taken as two indicators to evaluate the risk and hazard of battery explosion. Moreover, a safety assessment method was proposed based on the two indicators.
Therefore, the study of battery explosion needs to comprehensively consider the gas and heat production as well as its mechanical impact on the external environment. The goal is to propose effective targeted prevention and control strategies in automotive applications.

Li-ion batteries can create pressurized explosions within sealed enclosures due to thermal runaway (TR). Researchers at the National Institute for Occupational Safety and Health (NIOSH) measured TR pressures of lithium iron phosphate (LFP) cells as a function of free space within sealed enclosures and observed an inverse power relationship.
Annex E of IEC/EN 60079-1 defines lithium-ion cells (according to IEC 61960) as used in flameproof enclosures, and describes various requirements such as temperature, monitoring equipment, charging, etc. The cell or battery is accommodated in a case, or enclosure, that is able to withstand the explosion of a combustible gas from within.
In automotive application, an early warning schedule should be built in BMS, and effective protective measures against battery explosion should also be taken, especially under high current charging conditions. 4.
