One of the most critical risks associated with lithium-ion batteries is thermal runaway, a phenomenon that can lead to intense fires and explosions. This article delves into the mechanics of thermal runaway, its causes, consequences, and the measures to mitigate such hazardous events. What is Thermal Runaway?
The essence of thermal runaway mainly lies in the stability of anode and cathode materials and electrolytes. Intrinsic safety is the basis of battery safety, and the thermal stability of electrode materials is improved by doping and coating. The mechanical strength and thermal stability of diaphragm should be improved.
Effective LIB thermal runaway warning technology can not only improve the safety and reliability of the battery but also promote the use of clean energy and reduce the dependence on traditional energy, which is immeasurable for the development of human society.
First, by using battery management technology to detect the early warning signal of the system, the precise location where the abnormality occurs can be determined. Secondly, utilizing blocking technology to keep the number of thermal runaway modules within a certain range could be a useful approach.
