- Abstract
The use of perfluorinated hexanone as a fire extinguishing agent for lithium-ion batteries (LIBs) has been steadily increasing in China in recent years. It successfully handles the fire extinguishing problem of LIBs, however, it can additionally set off steel aluminum corrosion. Due to a variety of factors, this could result in secondary disasters following the storage or use of perfluorinated hexanone. To better understand the mechanism of perfluorinated hexanone corrosion on aluminum and the structure of the product, we investigated the molecular structure of the corrosion product ('aluminum powder') using a variety of chemical analytical methods and hypothesized the mechanism of occurrence. This will aid in the regulation of perfluorinated hexanone safety and the avoidance of secondary disasters.
