Lithium-ion battery fires surge globally, posing increasing risk
Lithium-ion battery fires are escalating worldwide due to increased usage and the prevalence of lower-quality devices. In the UK, fires doubled in three years, reaching 1,760 in 2025. Damaged or misused batteries are primary causes. Early detection and knowing how to respond are crucial for mitigating risks associated with these ubiquitous power sources.
Key points
- The UK saw a 147% increase in lithium-ion battery fires between 2022 and 2025, with 1,760 reported in 2025.
- Damaged, misused, or poorly manufactured batteries are the primary causes of lithium-ion battery fires.
- There were approximately 25,000 incidents involving fires or overheating related to lithium-ion batteries in the US over the last five years.
- Experts stress that early detection and knowing how to respond are crucial for mitigating risks associated with lithium-ion battery fires.
- The widespread adoption of battery-powered devices and lower-quality products are driving the surge in lithium-ion battery fires globally.
Lithium-ion battery fires are becoming a significant global concern, driven by the widespread adoption of battery-powered devices and a rise in lower-quality products. In the United Kingdom, fire departments responded to an estimated 1,760 lithium-ion battery fires in 2025. This figure represents a substantial increase of 147% over the preceding three years, indicating a rapidly growing trend.
These incidents are often linked to damaged, misused, or poorly manufactured batteries. The sheer volume of portable electronics, from smartphones and laptops to e-bikes and power stations, means these batteries are omnipresent. In the United States, data indicates approximately 25,000 incidents involving fires or overheating related to lithium-ion batteries over the last five years, spanning residential issues to industrial-scale events. Experts emphasize that understanding the risks and knowing appropriate response measures can be critical in managing these situations.
