Hess, Steffen; Wohlfahrt-Mehrens, Margret; Wachtler, Mario published the article 《Flammability of Li-Ion Battery Electrolytes: Flash Point and Self-Extinguishing Time Measurements》. Keywords: flammability lithium battery electrolyte flash point self extinguishing safety.They researched the compound: 2-Methylglutaronitrile( cas:4553-62-2 ).COA of Formula: C6H8N2. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:4553-62-2) here.
The flammability of electrolytes is an important aspect of the thermal safety behavior of Li-ion batteries. Flash points (FPs) and self-extinguishing times (SETs) of 25 solvents (including carbonates, ethers, esters, lactones, dinitriles, a sulfone, and others), 3 solvent mixtures, and 15 electrolytes are presented. The FPs have been measured according to the Abel and Pensky-Martens closed-cup methods using 12 mL of sample and elec. ignition. The SETs have been determined with the pure liquids, without any carrier substrates. A correlation of the FPs with the SETs, as well as with vapor pressures and b.ps. is attempted. Furthermore, the effect of the addition of two non-flammable solvents [1-butyl-1-methylpyrrolidinium bis(trifluoromethyl-sulfonyl)imide and Me nonafluorobutyl ether] and a flame-retardant additive (tri-Me phosphate) on both the SET and the FP of a carbonate-based electrolyte is discussed. As an alternative to their exptl. determination, the FPs of the pure solvents have been calculated from other phys. and chem. properties of the substance, and the FPs of the solvent mixtures and electrolytes from the FPs of their flammable constituents. Some of the models predict the FPs with an accuracy of ± 10°C, which may be sufficient to estimate the flammability hazards for many applications.
This literature about this compound(4553-62-2)COA of Formula: C6H8N2has given us a lot of inspiration, and I hope that the research on this compound(2-Methylglutaronitrile) can be further advanced. Maybe we can get more compounds in a similar way.
