Lithium Fluoroalkylphosphates

A new class of compounds known as lithium fluoroalkylphosphates was introduced [87-89]. The premise for their development was that the substitution of one or more fluorine atoms in LiPFe with electron-withdrawing perfluorinated alkyl groups should stabilize the P-F bond, rendering it stable against hydrolysis and resulting in an improved thermal stability of the salt. The hydrophobic perfluorinated alkyl groups sterically shield phosphorus against hydrolysis. The new compounds also have conductivity comparable...
