As e-vehicles are becoming more and more popular, e-vehicle&battery thermal insulation and fire prevention become big challenges to e-vehicle manufacturers.

E-Vehicle Power Battery Thermal Runaway Safety Hazards

Nowadays, we often hear about safety accidents caused by e-vehicle battery spontaneous combustion, e-vehicle collisions, and fires. In such accidents, battery thermal runaway hazards play a big role. New efficient thermal insulation and fire prevention materials are urgently needed to prevent high-temperature heat from spreading between adjacent battery cells and delay the potential thermal diffusion caused by the battery thermal runaway. Meanwhile, to prevent the heat and fire from spreading into the passenger cabin, it is essential to protect the outer coating of the battery pack from being ignited by high-temperature penetration.

Whole E-Vehicle Heat Insulation& Fire Prevention Problems

Firstly, in winter, e-vehicle battery packs can not work properly when the ambient temperature is too low. New efficient insulation materials are urgently needed for the heat insulation of e-vehicle battery packs to reduce the temperature drop rate.

Secondly, conventional combustible organic foaming thermal insulation materials inside e-vehicles will fuel the fire and produce a lot of toxic smoke, which will directly harm the respiratory and nervous systems of passengers, making it even more difficult for passengers to escape. New inorganic, nontoxic, and fireproof thermal insulation materials are urgently needed to restrain the fire spread, leaving passengers more time to escape.

Lastly, as there is only limited space for thermal insulation materials installation inside e-vehicles, especially inside the battery packs, it is impossible to install complex conventional thermal insulation materials. New ultra-thin, convenient, and efficient thermal insulation materials are urgently needed for e-vehicles.
