EV battery fires are worse, but 60 times less likely than gas car fires.
The fear of EV battery fires is often amplified by critics.
But when fires do occur in lithium-ion batteries, they can be more destructive — burning hotter, escalating quickly, and releasing toxic gases — creating a perception of heightened risk. Recent high-profile cases, such as the fire from a parked Mercedes EV, which used a battery made by Chinese maker Farasis Energy, in South Korea late last year have exacerbated fears. The fire took eight hours to extinguish and damaged around 880 other cars in the garage where the vehicle was parked.

This suggests that improvements to the EV’s base structure, using designs and materials that offer better shock absorption during collisions, could help enhance the safety of current lithium-ion batteries — without requiring a complete overhaul of existing battery technology.
