This week Americans and British passengers alike woke to the news of an unprecedented move. The US imposed a ban on selected electronic items on flights from selected airports in Africa and the Middle East and within hours the UK followed suit with a similar announcement. The significant difference was the inclusion of two of its airlines, British Airways and Easy Jet, in the UK’s list. On the contrary, the United States has not enforced the regulation on American airlines. The new regulation will take effect this weekend.
The ban makes headlines as it implies a notable change in travel convenience; passengers heading to the US will now have to check in their iPads, laptops, and other tablets. However, this move houses a glaring potential problem.
Most of today’s tech gadgets are powered by lithium batteries. Authorities have expressed concerns over the potential for these batteries to ignite mid-flight. But have they considered the fallout of such an explosion in the airplane’s cargo area, a space closer to the fuel tank and a more confined spot brimming with luggage that can easily be ablaze?

This is the predicament arising with such a decision and factually speaking, tackling such explosions might prove less difficult if they occur in plain sight within the plane cabin, potentially observed by trained professionals on board.
Stepping back in time, Sony was the first company to commercialize lithium batteries back in 1991. Since then, their usage has become prevalent in mobile phones and extended to remarkable feats such as powering Mars’ Curiosity rover, currently collecting data on Mars for NASA scientists. Lithium-ion batteries charge faster than their counterparts and can adapt to modern phone designs as their compact size can store a surprising amount of energy. As the lightest metal, lithium can conduct electricity faster than most, making it considered safe. However, we have witnessed phones, like the infamous Samsung Galaxy S7, and hoverboards, both utilizing this technology, cumulatively lead to numerous cases of ignition while charging.
Despite the secure reputation of lithium batteries, human design flaws often instigate their catastrophic detonations. Samsung publicly acknowledged that design flaws attributed to the battery manufacturer sparked the untimely termination of its Galaxy S7’s production. However, it’s crucial to understand that the fault doesn’t solely lie with the battery makers. Our relentless pursuit of smarter, smaller gadgets piles pressure onto lithium battery producers to manufacture smaller, high-capacity batteries. This compressed containment can damage the battery’s electrodes, which can subsequently result in short circuiting, ensuing in potential fire. Furthermore, this compact design leaves little room for battery cooling, causing batteries to overheat and potentially trigger a chemical reaction leading to an explosion.
Given the high stakes, the scenario becomes more fraught if we consider the likelihood of these lithium battery-powered gadgets inside the possibly heated and crowded compartment of an airplane.
Whilst it appears that the authorities are not blind to these potential threats, whether they have a foolproof contingency plan remains an open question. What seems more certain, however, is that explosions beneath the passenger area of the plane could pose a grave risk, far worse than the alternative.
