Lithium-Ion Battery Fires: The Silent Crisis Behind Everyday Tech

A devastating fire that tore through Glasgow’s Central Station last month has exposed a growing but little-understood technological hazard that’s keeping fire safety experts awake at night. The blaze, which continues to keep Scotland’s largest rail interchange closed, is believed to have originated in a vape shop—those seemingly harmless devices powered by lithium-ion batteries that have become ubiquitous in modern life.

“This is a new technology that comes with an unintended new hazard,” explains Guillermo Rein, professor of fire science at Imperial College London. “A lithium battery fire—in terms of how it develops, how we detect it, and how we suppress it—is completely different from the sorts of fires we’ve protected our homes against for decades.”

The statistics paint a concerning picture. London firefighters now respond to an e-bike or e-scooter fire every other day, with incidents jumping from just 12 in 2019 to over 200 in the most recent year. Across Scotland, lithium battery-related fires have surged from 20 to 69 in the same period. But experts warn these numbers likely represent just the tip of the iceberg, as there’s no comprehensive data collection system for these incidents across England and Wales.

What makes these fires particularly dangerous is the phenomenon of thermal runaway—a catastrophic chain reaction where a damaged or malfunctioning battery’s internal temperature spirals out of control. The result is a pressurized release of toxic gas that ignites into a blowtorch-like flame, often with little warning. Unlike conventional fires, these battery fires burn with an intensity that can breach multiple layers of fire protection in buildings.

Paul Christensen, professor of pure and applied electrochemistry at Newcastle University, puts it bluntly: “While the probability of a fire from a lithium-ion battery is very low, the hazard is very, very high. We’ve seen that with Glasgow.”

The risk extends far beyond e-bikes and vapes. These batteries power everything from smartphones and laptops to electric vehicles, power tools, and even children’s toys. Their energy density—the amount of power they can store relative to their size—makes them incredibly useful but also potentially dangerous when compromised.

The economic impact is staggering. Incorrect disposal of lithium batteries, which should never be placed in household waste, has caused serious fires in waste collection vehicles and recycling facilities across the UK. The annual cost of these incidents is now estimated at over £1 billion, not to mention the injuries to waste management workers.

The vape industry, already under scrutiny for its health impacts, is now facing questions about fire safety. The UK Vaping Industry Association is calling for stricter licensing requirements that would mandate proper age verification, legal product sourcing, recycling systems, and electrical safety understanding for retailers.

The National Fire Chiefs Council has raised alarms that the rapid adoption of lithium-ion technology is outpacing the development of safety standards. “When these batteries fail, they can fail catastrophically,” warns Richard Field, the council’s electrical safety lead. “Fire chiefs have been clear that stronger product safety rules, tighter oversight of online sales, and effective enforcement are needed.”

Public education remains a critical gap. Many consumers remain unaware of the specific risks or proper handling procedures for devices containing these batteries. Simple actions like using the correct charger, avoiding extreme temperatures, and proper storage can significantly reduce fire risks, but awareness is lacking.

The reluctance to address these hazards appears to span both government and industry. Christensen notes a concerning hesitation at governmental levels to acknowledge the problem, while Rein observes that the battery industry “has never had an issue with safety before” and seems slow to adapt to this new reality.

As our world becomes increasingly powered by lithium-ion technology, the challenge of balancing innovation with safety grows more urgent. The Glasgow fire serves as a stark reminder that the devices we rely on daily carry risks we’re only beginning to understand and regulate.
