Lots and lots of EV fires, and they can’t extinguish them. They need to wait about four hours for it to burn out. Why are lithium-ion battery failures so dangerous? The thermal runaway phenomenon means lithium-ion battery fires are extremely hard to put out. Water-based fire extinguishers will cool down the battery to help prevent the spread of the fire but will not extinguish the fire on the battery until its energy is dissipated. Special lithium-ion gel extinguishers do exist but are not yet widely available for all lithium-ion battery applications. And even when a lithium-ion battery fire appears to have been extinguished, it can reignite hours – or sometimes even days – later. Lithium-ion batteries can also release highly toxic gases when they fail, and excessive heat can also cause them to explode. unsw.edu.au
