– A lithium battery would be able to contain enough energy to release the kind of damage I have seen in the videos from Lebanon, says Gilljam, who works at the Norwegian Defense Research Institute (FFI).
He says the researchers at FFI have caused many batteries to explode, but do not know how it could possibly have been caused from a distance.
– The batteries must either be heated, physically damaged, or overcharged much more than they can withstand to achieve such a reaction. If it is the battery that causes the explosions, it is reasonable to believe that it has been triggered by something in the pager or inside the battery itself which is designed for this, says the researcher.
A short circuit in a battery could lead to the development of gas inside the battery. In a battery shaped like a metal cylinder, this could cause a rapid build-up of pressure and trigger an explosion.
Batteries in mobile phones, on the other hand, are different. Gilljam can reassure anyone worried about sleeping with their mobile phone on their bedside table after Tuesday’s events in Lebanon.
– However, it is not recommended that you charge it while you sleep, he emphasizes.
A mobile battery is designed like a pouch cell, so that the pressure cannot build up to the same extent and explode.
– However, it is not harmless, and both fire and toxic and flammable gas can come out, he says.
But not an explosion, like what happened with hundreds of hand-held pagers in Lebanon on Tuesday.

Lithium Battery Explosions: The Science Behind the Devastating Damage
In the wake of recent explosions in Lebanon, many have questioned the cause of the devastating damage. Researchers at the Norwegian Defense Research Institute (FFI) have shed light on the possibility of lithium batteries being the culprits. But how exactly can a lithium battery contain enough energy to cause such destruction? In this article, we’ll delve into the science behind lithium battery explosions and the conditions necessary for them to occur.
Understanding Lithium Battery Explosions
Lithium batteries, widely used in portable electronics, are designed to store a significant amount of energy. However, under certain conditions, this energy can be released rapidly, resulting in a catastrophic explosion. According to researcher Gilljam at FFI, “A lithium battery would be able to contain enough energy to release the kind of damage I have seen in the videos from Lebanon.”
Conditions for Explosion
So, what triggers a lithium battery explosion? Researchers have found that batteries must be subjected to one of three conditions to explosion:
- Heat: Lithium batteries can be prone to overheating, particularly when charged or discharged rapidly. If the battery is heated beyond its designed temperature range, the risk of explosion increases significantly.
- Physical Damage: Physical damage to the battery, such as a puncture or crush, can cause a short circuit and lead to an explosion.
- Overcharging: Overcharging a lithium battery beyond its designed capacity can cause the battery to become unstable, increasing the risk of explosion.
The Role of Short Circuits
A short circuit in a lithium battery can lead to the development of gas inside the battery. In a battery with a metal cylindrical design, this gas buildup can cause a rapid increase in pressure, ultimately triggering an explosion. Researchers at FFI have caused many batteries to explode, but they remain puzzled about how such an explosion could be triggered remotely.
Design Features and Safety Measures
Mobile phone batteries, for instance, are designed with safety features to prevent such explosions. These batteries are typically protected with built-in safety mechanisms, such as thermal cutoffs and protective circuits, to prevent overheating and overcharging.
Conclusion
While lithium battery explosions can be devastating, the science behind them is complex and multifaceted. Researchers at FFI have shed light on the conditions necessary for such explosions to occur, highlighting the importance of design features and safety measures in preventing these incidents. As our reliance on portable electronics continues to grow, understanding the risks and taking steps to mitigate them is crucial.
FAQs
Q: Can a lithium battery explosion be triggered remotely?
A: Researchers at FFI have not found a way to trigger a lithium battery explosion remotely, suggesting that any explosion would require physical damage, overheating, or overcharging.
Q: Are mobile phone batteries safer than other lithium batteries?
A: Yes, mobile phone batteries are designed with built-in safety features to prevent overheating and overcharging, making them less prone to explosion.
Q: What can be done to prevent lithium battery explosions?
