Abstract: Lithium batteries have been rapidly popularized in energy storage for their high energy density and high output power. However, due to the thermal instability of lithium batteries, the probability of fire and explosion under extreme conditions is high.
With the flammable battery vent gas (BVG) being a key factor that causes delayed explosions in confined spaces, there is a great need to understand and predict the combustion and explosion behavior of BVG. The BVG mainly comes from the thermal runaway of lithium-ion batteries.
