(1) High temperature rise rate. Batteries can spontaneously react exothermically under abuse. When the contact heating is out of control, the internal exothermic reaction of the battery is fierce, and a large amount of heat is generated in a short time, making the battery temperature rise sharply. During thermal runaway, the maximum temperature rise rate of the battery even exceeds 100 ℃/s and the surface temperature exceeds 1000 ℃. Such a high temperature far exceeds the ignition point of other combustible materials inside and outside the battery module, which is easy to cause a larger fire accident;
(2) With intense jet fire and high heat release rate. With the rise of temperature, the chemical reaction inside the battery is intensified and a large amount of gas is released. The gas is continuously accumulated inside the battery, resulting in the gradual increase of internal pressure. When a certain threshold is reached, the battery safety valve breaks and a large amount of combustible gas, electrolyte and material particles are ejected, resulting in fierce jet fire, and the flame height can even reach 1-2 m.
(3) Fast fire spread. When a battery in the battery module is out of control due to contact heating due to failure, the closely arranged arrangement can quickly transfer the heat to the adjacent battery, causing the thermal runaway transmission in the battery module and causing catastrophic consequences.
(4) It is difficult to put out the fire and the fire is easy to rekindle. During thermal runaway, most of the exothermic reactions occur inside the cell. Due to the enclosure, it is difficult for the fire extinguishing agent to enter the battery to block the thermal runaway chain reaction. Therefore, during the fire extinguishing process, the battery still generates heat continuously, which makes it difficult to put out the fire. Even if the fire is successfully extinguished, if the battery temperature cannot be completely reduced and the heat source can be eliminated, it is still difficult to suppress the internal chemical reaction. At this time, the three elements of ignition source, combustible and oxidizing agent are not eliminated, and the battery fire is easy to re-ignite after the release of extinguishing agent.
(5) Fire with explosion risk. The thermal runaway process generates large quantities of gases, including CO, CO2, CH4, C2H4, H2 and electrolyte vapors.
(6) Hot runaway gases are toxic. In addition to being combustible and explosive, the gas generated in battery fire is also toxic to some extent, which is one of the main causes of casualties. CO is one of the most toxic gases in a fire, competing with oxygen for hemoglobin in the blood, reducing the oxygen supply capacity of hemoglobin and causing hypoxia damage to human tissues.

By using multiple sensing sensors and AI algorithms, comprehensive monitoring of complex environments and device states can be achieved. Based on the characteristics of different stages of battery thermal runaway, corresponding data is collected through sensors such as smoke, temperature, humidity, carbon monoxide, carbon dioxide, hydrogen, etc., and AI algorithms are used to logically analyze and process the changes in different stages of battery thermal runaway, thereby achieving monitoring, warning, linkage control and fire extinguishing of early states of battery thermal runaway.
