Which of the following devices is associated with lithium battery fires?

Smartphones are commonly associated with lithium battery fires due to the use of lithium-ion batteries that power these devices. These batteries have a higher energy density, which makes them efficient but also susceptible to overheating, especially if there is a manufacturing defect, physical damage, or exposure to extreme temperatures. When a lithium-ion battery fails, it can lead to thermal runaway, resulting in smoke, fire, or even explosion.

In contrast, while other devices like refrigerators, televisions, and toasters may utilize various forms of energy sources and components, they either do not primarily rely on lithium batteries or do not face the same level of risk regarding battery-related fires. This specificity towards smartphones illustrates the importance of recognizing which consumer electronics pose a significant fire risk due to their reliance on lithium-ion technology.
