At a certain level, the chemical reaction creates thermal runaway, causing rapid overheating and quickly affecting adjacent cells. Batteries will spontaneously ignite, burning at extremely high temperatures of between 700◦c and 1000◦c, and releasing dangerous off gases that in enclosed spaces can become a flammable vapour cloud explosion (VCE).
To avoid battery explosions, it is important to follow certain precautions. Firstly, always use the recommended charger for your device and avoid overcharging the battery. Make sure to unplug the device once it is fully charged. Secondly, avoid exposing the battery to extreme temperatures, as high temperatures can increase the risk of explosion.
When a lithium-ion battery fire breaks out, the damage can be extensive. These fires are not only intense, they are also long-lasting and potentially toxic. What causes these fires? Most electric vehicles humming along Australian roads are packed with lithium-ion batteries.
There are several factors that can contribute to a battery explosion. One common cause is overcharging. When a battery is overcharged, it can’t handle the excessive amount of electrical energy, resulting in the release of flammable gases. These gases can build up inside the battery and eventually lead to an explosion.
Puncturing a lithium-ion battery can release flammable electrolyte, which can ignite and cause a fire. Avoid exposing the battery to water or other liquids. Liquid contact can damage the internal components and potentially lead to a short circuit, which can then cause the battery to ignite or explode.
The Science of Fire and Explosion Hazards from Lithium-Ion Batteries sheds light on lithium-ion battery construction, the basics of thermal runaway, and potential fire and explosion hazards.
