Lithium-ion battery (LIB) is one of the most promising electrochemical devices for energy storage. The safety of batteries is under threat. It is critical to conduct research on battery intelligent fire
China Power Grid is actively building a new energy-based ultra-high voltage grid system. Therefore, the researches on fire safety of power grid are of great importance. This paper firstly investigates the fire accident
FM-200 is the brand name for a fire suppression agent known as heptafluoropropane (chemical formula: C3HF7). It is a colorless, odorless gas that is used in fire suppression systems, especially in areas where water
The depletion of fossil energy resources and the inadequacies in energy structure have emerged as pressing issues, serving as significant impediments to the sustainable progress of society
Gas fire-extinguishing agents such as Halons, HFC-227ea, CO 2 and Novec 1230 are beneficial to integrity protection of battery system during the fire extinguishing process. However, gas fire-extinguishing agents could not effectively reduce the temperature of battery.
A high heat capacity is most essential characterization parameter for reducing the temperature of battery. Obviously, water-based fire-extinguishing agents possess excellent cooling capacity. Among water-based fire-extinguishing agents, the durable heat capacity of F-500 is highest, followed by water and foams.
Gas fire extinguishing agents have the advantages of no residue, environmental friendliness, and no damage to equipment. At present, the gas fire extinguishing agents for battery fires mainly include halon, carbon dioxide, heptafluoropropane, dodeca-fluoro-2-methylpentan-3-one, and 2-BTP new gas fire extinguishing agents.
The fire extinguishing system is a significant part to extinguish fires in progress and prevent the spread of fires . The fire extinguishing system is usually in standby mode and is controlled by the signal processing system. When a fire occurs, the built-in fire extinguishing agents are released for extinguishing.
Gas Fire Extinguishing Agent Gas fire extinguishing agents have the advantages of no residue, environmental friendliness, and no damage to equipment.
With the aim to rapidly extinguish the LIBs fire, an effective LIBs fire suppressant is require to be developed. Gas fire-extinguishing agents such as Halons, HFC-227ea, CO 2 and Novec 1230 are beneficial to integrity protection of battery system during the fire extinguishing process.
