The Growing Danger of Lithium Battery Fires

In recent years, the use of lithium-ion batteries in everyday devices has surged. From smartphones, head torches, GPS, sports watches, e-bikes and lanterns, these batteries are valued for their high energy density and long life. However, with this widespread adoption it is clear to see that these devices in the cycling, running, fitness and outdoor industries, bring increasing concerns about safety, particularly the risk of fires.

The London Fire Brigade has highlighted a troubling trend: a significant rise in fires caused by e-bikes and e-scooters, with a 78% increase in incidents in 2023 alone. This spike is not isolated; similar patterns are being observed globally. The main culprit is the lithium-ion batteries powering these devices.

Causes of Fires from Lithium-Ion Batteries

Lithium-ion batteries are prone to a phenomenon known as thermal runaway, where the battery’s temperature rapidly increases, leading to fires or even explosions. Several factors can trigger this:

Overcharging: Exceeding the recommended charge can cause overheating.

Physical Damage: Any damage to the battery can disrupt its internal components, increasing the risk of fire.

Short-Circuiting: Faulty wiring or manufacturing defects can lead to internal short circuits.

Improper Storage: High temperatures or moisture can increase fire risks.

The Impact on the Running, Cycling and Outdoor Industries

As more fitness devices are powered by lithium-ion batteries, the potential for fire hazards increases. Without proper precautions, individuals, clubs and businesses face significant safety threats that can endanger employees and property. A devastating fire could jeopardise operations, making it essential to implement safety measures to protect people and properties.

Safety Measures to be Implemented

To mitigate these risks, comprehensive risk assessments and safety protocols are crucial. Key recommendations include:

Proper Storage: Store batteries in cool, dry environments and avoid stacking them in ways that could cause damage.

Regular Maintenance: Regularly inspect and maintain devices and batteries to prevent wear and tear that could lead to fires. Implementing Battery Management Systems (BMS) can help monitor battery health and prevent overheating.

Employee Training: Educate staff about the risks and proper handling of lithium-ion batteries to ensure safe practices.

Fire Suppression Systems: Install appropriate fire suppression systems that can handle lithium-ion battery fires, which are difficult to extinguish with conventional methods.

As the use of lithium-ion batteries continues to grow, so does the importance of understanding and mitigating the associated risks. The sport and leisure industry must remain vigilant and proactive in its approach to safety, ensuring that the benefits of this powerful technology do not come at the cost of increased fire hazards.
