Experimental Study on Microemulsion and Deionized Water for 4S4P Lithium-Ion Battery Pack Fires
Thermal runaway of lithium-ion batteries has always been a safety hazard in the field of electric vehicle and energy storage systems. An effective and feasible method is urgently needed to prevent or mitigate the risks caused by battery thermal runaway. Water mist is an effective means to suppress the thermal runaway of lithium ion batteries. This work studies and compares the suppression of deionized water mist and microemulsion water mist on the thermal runaway fire of lithium ion batteries. By adjusting the different positions of the nozzle, the fire extinguishing and cooling capacity of two fire extinguishing agents were revealed and compared. The results indicate that the position of the nozzle has a significant impact on battery pack fires. Under the condition that the extinguishing agent can completely cover the battery, the microemulsion extinguishing agent can quickly cool and extinguish the fire. Its cooling capacity is about 2.5 times that of deionized water, and the extinguishing time is only 1/10 of that of deionized water. The low surface tension of the microemulsion allows the liquid to be released with small droplets under high pressure, forming a dense barrier to isolate external oxygen and better penetrate into the battery pack. The additives in the microemulsion can effectively combine with the free radicals in the fire to quickly extinguish the flame.
期刊介绍：
Fire Technology publishes original contributions, both theoretical and empirical, that contribute to the solution of problems in fire safety science and engineering. It is the leading journal in the field, publishing applied research dealing with the full range of actual and potential fire hazards facing humans and the environment. It covers the entire domain of fire safety science and engineering problems relevant in industrial, operational, cultural, and environmental applications, including modeling, testing, detection, suppression, human behavior, wildfires, structures, and risk analysis.
The aim of Fire Technology is to push forward the frontiers of knowledge and technology by encouraging interdisciplinary communication of significant technical developments in fire protection and subjects of scientific interest to the fire protection community at large.
It is published in conjunction with the National Fire Protection Association (NFPA) and the Society of Fire Protection Engineers (SFPE). The mission of NFPA is to help save lives and reduce loss with information, knowledge, and passion. The mission of SFPE is advancing the science and practice of fire protection engineering internationally.
