New energy vehicles are influencing the development of the global automobile market. With the policy of banning the sale of traditional fuel vehicles being put on the agenda, the importance of new energy vehicles is also increasing. Although pure electric vehicles are environmentally friendly compared to traditional cars, their own drawbacks are becoming more and more well-known - prone to spontaneous combustion. According to incomplete statistics, more than 50 new energy vehicle fires occurred in 2018, and most of the accidents were caused by battery circuit problems, and the fire spread from the battery bin all the way to the vehicle and finally left only a frame.

So is there a good way to improve the existing shortcomings of new energy vehicles? The answer is to use aerogel insulation felt. Aerogel has been hailed by the scientific community as one of the "10 magic materials that change the world", it not only has the reputation of the world's lightest solid, only 0.16mg per cubic centimeter, and the interior is 99.8% air, with very good fire insulation effect. It is the super adiabatic performance of nanopore based on aerogel that has great potential application value in the field of new energy.

The operating temperature range of the lithium battery is maintained at -20℃-60℃, and the humidity control should be below 1%, which can provide the most suitable working environment for the lithium battery and ensure its service life. The best solution is to lay aerogel felt between battery modules and modules. The first advantage of the aerogel is its excellent fireproof performance (Class A fireproof, smoke-free, non-combustible), which can cut off the contact between other battery modules and the fire source when a battery is short-circuited to minimize the loss. Secondly, in winter, the excellent thermal insulation performance of aerogel can also provide the best working temperature for the battery to ensure the maximum performance of the battery. On the other hand, the aerogel felt isolation layer is laid between the car battery compartment and the passenger cabin. When the car parts burn, the aerogel felt can prevent the fire from spreading and win the escape time for the passengers.
