Some of these batteries have experienced troubling fires and explosions. There have been two types of explosions; flammable gas explosions due to gases generated in battery thermal runaways, and electrical arc explosions leading to structural failure of battery electrical enclosures.
According to the characteristic of parameters, the sensitivity and severity were taken as two indicators to evaluate the risk and hazard of battery explosion. Moreover, a safety assessment method was proposed based on the two indicators.
While the flammable, high energy and active material increase their dangers of fire and explosion. The fuel, oxygen and energy can exist in the battery system, which provide the necessary contributions to the combustion triangle, thus there is the possibility of fire and explosion.
From the perspective of battery safety management, we can prevent the occurrence of explosion and fire by removing and isolating the air in the automotive application. After passing the negative maximum pressure (P−max = 0.448 MPa), the pressure rose sharply and reached the positive maximum pressure (P＋max = 0.997 MPa) in less than a second.
During the TR process, the battery releases flammable and toxic gases and may start a fire or cause an explosion –. The knowledge of fire behavior is important for improving safety and preventing accidents involving batteries. A uniform way of performing tests and documenting fire behavior are under development.
