With the rapid development of new energy vehicles in recent years, the number of electric vehicles has increased dramatically. However, safety issues have become increasingly serious. In pursuit of higher range and charging efficiency, the energy density of power batteries has been increasing. But this is a double-edged sword. The destructive power brought about by excessive energy density when thermal runaway occurs is alarming. Therefore, in order to ensure the safety of occupants, the Ministry of Industry and Information Technology (MIIT) integrated a number of relevant national recommended standards and international standards and officially released a national mandatory standard in 2020 - GB 38031-2020 "Electric Vehicles Traction Battery Safety Requirements", which stipulates the safe escape time for occupants.

In order to reduce the hazards caused by thermal runaway of batteries, power battery-related safety research must be vigorously carried out. For the thermal runaway of new energy vehicle battery pack, Rongtai has independently developed a series of mica products for thermal-protection and proposed a supporting passive thermal runaway protection solution to achieve effective isolation between the internal layers of the battery, the battery pack and the occupant compartment, to resist the impact of thermal runaway, slow down the spread of thermal runaway and significantly extend the safe escape time, building a solid wall for the occupants.
