When batteries die, they can kill you
Posted On July 1, 2021
Batteries can go bad in two different ways.
When the cells are damaged or lose their charge, they may become unstable, which can cause them to explode.
But if the cells can no longer supply power to the electronic devices they are attached to, they’ll become unstable again, eventually leading to overheating and eventually the battery being damaged beyond repair.
When this happens, the batteries may simply stop working altogether, causing a power loss or a loss of data.
The two worst scenarios can cause a battery to go into meltdown.
“The good news is that most of the time, you can recover,” said Jeff Strain, director of the University of Ottawa’s Centre for Battery and Energy Systems.
“We have some very good tools to help you.”
In addition to a variety of tools available online, the University Of Ottawa is developing its own battery recovery program, which will be launched next spring.
The program is also a joint venture between the university and the company that manufactures the battery terminals.
“I think the whole industry will benefit,” Strain said.
“People will start to see that there is something out there that’s really really good.”
While there are no definitive tests on how well a battery can recover from an overheating, Strain believes there are plenty of reasons to be concerned.
“Most of these devices are very small and very fragile.
It’s not uncommon for a battery that is about 20 per cent or 30 per cent of its original capacity to lose its charge and have to be replaced,” he said.
In addition, the amount of energy consumed by the device during its initial charge could be affected.
“If it’s only one day’s charge, then it’s unlikely that the battery is going to be able to recover,” he added.
“But it’s also very possible that the device is going overheat.”

It holds the battery and allows it to charge and discharge.
A battery leaf battery is a battery terminal that is attached to an electronic vehicle.
When it is attached, it holds a small amount of lithium in place that is charged when the vehicle is started.
If the battery goes into meltdown, the battery can either be replaced or lost entirely.
When a battery is overheat, it loses power.
“Overheating is the only way to cause a voltage drop or a short circuit,” said Strain.
“So even if you don’t have a device that’s capable of starting a car, a device like a battery, even if it’s just holding a small portion of a battery could become unstable and go into a runaway.”
Strain pointed out that the batteries that power electric vehicles are also designed to operate at temperatures higher than 40 degrees Celsius.
“That means that they’re going to experience some voltage drop, which is why they’re designed to be as small as possible and as safe as possible,” he explained.
In the event of a runaway, the damage can lead to serious injury, including amputation or even death.
A recent study by University of Pennsylvania’s Center for Energy and Environment found that in 2013, the US was responsible for the third-highest number of battery-related deaths in the world.
“In many ways, the situation is similar to the car industry,” Stryf said.
The University of Notre Dame’s Strain and Strain agree that it’s important to remember that overheating can also be a health hazard.
“At the end of the day, the more we understand about how overheating happens, and what the risk is for those who are using these batteries, the better the technology is going a long way,” Stress said.
