Exploding smartphones to electric vehicle fires, something is cooking and it’s the lithium battery. But humans are aiming to find habitable exoplanets in space meanwhile here on Earth basic utilitarian items like smartphones and EVs are spontaneously combusting. Why does this happen? and how to mitigate the risks is what this article looks at.
batteries have been a game changer for humanity, these compact, dense and power packed cells provide high energy in small sizes to power anything and everything. From tiny racing drones, smartphones, and electric vehicles to even the James Webb Space Telescope, it’s all powered by lithium-ion batteries.
While there are other types of batteries as well, such as Nickel Metal Hydride (NiMH) and typical Lead acid batteries, it is the power density of lithium ion batteries that makes them popular. A typical lithium ion battery stores up to 150 watt-hours of electricity in 1Kg of battery, a NiMH battery is able to pack around 100 watt-hours per kg, and the lead acid battery packs around 25 watt-hours per kg.
However, there are a few challenges with lithium batteries, firstly it uses rare materials like Cobalt, so they are expensive. The second challenge is heating and recently, lithium-ion devices catching fire are in the news more often.
Why do lithium batteries catch fire?
Lithium batteries are sensitive to high temperatures and are inherently flammable. Heat also plays a role in degrading a lithium ion battery faster than normal. The high density means they can also explode. However, it is usually a bad battery management system, poor design, or some external issues like cell punctures that lead to fire accidents. External factors such as rising temperatures are rarely the reasons behind battery fires, however, they can degrade battery life and performance.
Lithium ion batteries are prone to ‘thermal runaways’, a chain reaction of sorts, which is accelerated by high temperatures, and releases energy back, this excess energy further increases the temperature, and the cycle continues to lead to a destructive outcome. In extreme cases, thermal runaway can cause batteries to explode and start fires. In minor cases, it can cause the batteries to melt or be damaged beyond repair.
In most electric vehicles, we see a ‘cooling system’. This cooling system is only there to keep the lithium ion batteries cool. Smartphones and other gadgets have much smaller capacity lithium-ion batteries compared to EVs, so they don’t require external cooling. Smartphone batteries face problems with excessive heat due to perhaps an overheating processor, structural damage due to bending, or damage or overcharging.
Most cases of smartphone battery explosions or fires stem from either a poorly designed battery or physical damage. Battery designs have improved over time, however, physical damage is unpredictable and can cause the battery to burst into flames. Let’s say you drop your phone on a concrete pavement, bending the chassis a little, while externally the damage seems small, internally the bend can puncture the battery and it becomes a ticking timebomb. Smartphone users should also refrain from disassembling the battery component by themselves. Inserting or puncturing lithium ion batteries is dangerous and should not be attempted.
While the latest smartphones and laptops come with adaptive charging and battery health features, it is always advisable to use chargers compatible with the devices. Devices should never be charged under direct sunlight or in areas with high temperatures such as heaters and radiators, similarly covering your smartphone by placing it under a pillow while charging is also not advisable .
Smartphone fires or explosions are very rare, in fact, they are rarer than EV fires, as almost everyone uses some kind of smartphone while EV owners are few and far between. between them.
