While lithium-ion batteries are, on the whole, incredibly safe they do very very occasionally catch fire or explode. When it happens, like with Samsung’s Galaxy Note 7 fiasco or HP’s more recent laptop recall, it’s always big news. So what’s going on and why do batteries sometimes go out with a bang? Let’s find out.
When it’s released all in one go, the battery can explode. The lithium-ion battery from a Japan Airlines Boeing 787 that caught fire in 2013. Most lithium-ion battery fires and explosions come down to a problem of short circuiting. This happens when the plastic separator fails and lets the anode and cathode touch.
In severe cases, it can cause the battery to rupture and explode. Bending a lithium battery or subjecting it to a strong impact can cause internal deformation. This deformation can lead to mechanical failure of the battery’s components and create conditions ripe for thermal runaway, where the battery heats uncontrollably.
In summary, understanding the factors that lead to lithium battery fires and explosions—such as manufacturing defects, mechanical injury, poor storage environment, overcharging, overdischarging, and external short circuits—is crucial for maintaining safety.
Overheating is one of the main causes of lithium-ion battery failures, although physical damage to the battery can also lead to problems. Excessive heat — for example from using a faulty charger and overcharging the battery, or due to a short circuit — can damage the battery cell internally and cause it to fail.
That brings us to the aftermath of the fire – and another often-overlooked hazard: toxic fumes. When lithium-ion batteries catch fire in a car or at a storage site, they don’t just release smoke; they emit a cocktail of dangerous gases such as carbon monoxide, hydrogen fluoride and hydrogen chloride.
