Fires caused by lithium-ion batteries are on the rise, and it's a problem that's only going to get worse as more and more of our devices become battery-powered. From electric scooters to smartphones, these rechargeable batteries can pose a serious fire risk if not handled properly. Fortunately, there are some simple steps you can take to minimize the danger and charge your devices safely.
The Increasing Fire Hazard
According to experts, the number of fires caused by lithium-ion batteries has been steadily increasing in recent years. This is likely due to the growing popularity of battery-powered devices, as well as the higher energy density of newer battery technologies. In Sweden, for example, the number of battery-related fires has more than doubled since 2017.
These fires can be particularly dangerous because lithium-ion batteries can rapidly release their stored energy in an uncontrolled way, leading to intense heat, flames, and even explosions. This can happen if the batteries are damaged, overcharged, or subjected to extreme temperatures.
The consequences can be severe. Battery-related fires have resulted in injuries, property damage, and even fatalities in some cases. It's a problem that affects everyone from individual consumers to businesses and first responders.
Charging Safely at Home
Fortunately, there are some simple steps you can take to reduce the fire risk when charging your devices at home. One of the most important things is to never leave a device unattended while it's charging, especially overnight or when you're not at home.
It's also crucial to avoid charging devices on soft surfaces like beds or couches, as this can prevent proper airflow and cause the battery to overheat. Instead, charge your devices on a hard, flat surface and make sure there's plenty of space around them for air circulation.
"Lithium-ion batteries are a very energy-dense technology, and that means they can also be a fire hazard if not used properly," said Klas Berghede, an electrical engineer and battery expert.
Another important tip is to keep an eye on the battery's temperature during charging. If it starts to feel unusually warm, stop charging immediately and let it cool down before resuming. Overheating can lead to thermal runaway, a dangerous chain reaction that can cause the battery to catch fire.
It's also a good idea to only use the charger that came with your device, or a high-quality replacement from a reputable brand. Cheap, knockoff chargers may not have the necessary safety features to prevent overcharging or other issues.
Charging Away from Home
Charging your devices while you're out and about can be even riskier, as you have less control over the environment. Avoid charging your electric scooter or bike in hallways or other public spaces, as these areas may not have adequate ventilation.
Instead, try to charge your devices in a well-ventilated area, or even outdoors if possible. And be sure to keep an eye on the battery's temperature and disconnect the charger as soon as the device is fully charged.
If you're using a public charging station, be extra cautious. These stations may not have the same safety features as the charger that came with your device, and they could potentially overcharge or damage the battery.
Maintaining Batteries
Proper battery maintenance can also help reduce the fire risk. Avoid exposing your devices to extreme temperatures, whether hot or cold, as this can degrade the battery and make it more prone to issues.
It's also a good idea to avoid letting your devices' batteries completely drain before recharging them. Repeatedly running the battery down to zero can reduce its lifespan and increase the risk of problems.
By following these simple tips, you can help keep your home and your family safe from the dangers of lithium-ion battery fires. Remember, a little bit of caution can go a long way when it comes to charging your devices.
And if you do experience a battery-related fire, it's important to know how to respond. Never use water to try to extinguish a lithium-ion battery fire, as this can actually make the situation worse. Instead, use a dry chemical or carbon dioxide fire extinguisher, and evacuate the area immediately.
"Lithium-ion batteries are a very energy-dense technology, and that means they can also be a fire hazard if not used properly," said Klas Berghede, an electrical engineer and battery expert.
By taking these precautions and staying vigilant, you can help keep your home and your loved ones safe from the growing threat of lithium-ion battery fires. It's a small price to pay for the convenience and power these amazing batteries provide.
So the next time you plug in your phone, your scooter, or any other battery-powered device, take a moment to think about fire safety. With a little bit of care and attention, you can enjoy the benefits of these amazing technologies without putting your home at risk.
