The battery consists of electrolyte, separator, electrode and shell, the traditional flame retardant method of battery is to modify the components to improve its flame safety.
New battery flame retardant technologies and their flame retardant mechanisms are introduced. As one of the most popular research directions, the application safety of battery technology has attracted more and more attention, researchers in academia and industry are making efforts to develop safer flame retardant battery.
Flame retardant modification of electrolyte for improving battery safety is discussed. The development of flame retardant battery separators for battery performance and safety are investigated. New battery flame retardant technologies and their flame retardant mechanisms are introduced.
In summary, a highly effective way to improve the safety of LIBs is to use flame-retardant additives in electrolytes. The non-flammable solvent and the water-based electrolyte are both completely non-flammable. Flame retardant additives increase the flash point of the conventional electrolyte. This slows the spread of fire in the battery.
From this point of view, lithium oxalate is more favorable as a flame retardant than sodium fumarate or malonate. Table 6. Gas formation of FR compounds. Gas volumes were calculated by assuming ideal behavior (1 mol equals to 22.4 L). A total of 100 g was converted to mol, and the molar equivalents of CO and CO 2 were determined.
