Additionally, there are no doubt potential fire risks during the collection, recycling, treatment and disposal of batteries and EVs. This risk is linked to the SOC and capacity of the considered LIB. Cumulated battery bulks and EVs have a lower self-ignition temperature or a higher self-ignition risk.
This risk is linked to the SOC and capacity of the considered LIB. Cumulated battery bulks and EVs have a lower self-ignition temperature or a higher self-ignition risk. Thus, the fire risk is likely to increase during the collection of batteries and the disposal of EVs [63,64]. Environmental concerns also relate to fire-water run-off.
Thermal Runaway and Battery Fire: EV fires can be caused by battery failure, and the most common failure of LIB is the thermal runaway. Thermal runaway is a widely observed phenomenon in chimerical and combustion processes, referring to an overheating event in which exothermic chain reactions take place and overcome the cooling [53,74,75].
This increase in fire risk is proportional to the increase in the mass and capacity of the battery (or the fuel). During the burning of LIBs, the generation of flammable/explosive gases and toxic smokes, such as hydrogen (H2), methane (CH4), carbon monoxide (CO), and hydrogen fluoride (HF), can pose a threat to those involved [72,73].
Compared to the electrical energy stored in the battery, the thermochemical energy released from the battery fire, including both the thermal runaway heat inside the battery (i.e., the internal heat) and flame sustained by the flammable gases injected from the battery (i.e., the flame heat), is much higher [18,39,40].
New energy vehicle fires were developing rapidly. Once a fire occurs in the lithium-ion battery in the vehicle, the high-temperature smoke and CO, etc. seriously endangered the safety of people inside the vehicle and the tunnel. It would reach a very dangerous situation in a short time.
