Limited Scope: The article focuses on fire officials' concerns in San Diego, but doesn't provide national data to definitively show a rise in lithium-ion battery fires.
Focus on Small Devices: The fire official highlights micro-mobility devices, not necessarily a significant increase in overall fires. More devices on the road simply means a higher chance of incidents being reported.
Comparison with Gas-Powered Vehicles: While acknowledging the potential for future EV fires, the theory ignores the established dangers of gasoline fires. Gas fires release a wider range of toxic fumes and are statistically more common than EV fires, causing significant property damage and injuries.
Misinterpretation of EMF Impact: The scientific study referenced discusses the effect of strong, external magnetic fields on battery charging and discharging. Everyday exposure to weak EMF from power lines or phones is unlikely to cause thermal runaway.
Industry Advancements: Battery technology is constantly evolving. Manufacturers like Tesla are implementing strategies (larger cells, magnetic shielding) to mitigate fire risks.
Alternative Explanation:
The increase in reported lithium-ion battery fires could be due to a combination of factors:
Growing Popularity: As more devices and vehicles use lithium-ion batteries, the overall number of potential fire incidents naturally increases.
Heightened Awareness: Public awareness of lithium-ion battery risks might lead to more incidents being reported, even if the actual rate hasn't changed significantly.
Conclusion:
While lithium-ion battery fires do pose a risk, it's important to consider the bigger picture. Further research is needed to understand potential long-term effects of EMF on batteries. However, focusing on the established dangers of gas-powered vehicles and the safety improvements in battery technology suggest a more balanced perspective.
