The Uses of METHYL DIFLUOROACETATE
A methyl difluoroacetate (MFA)-based LiPF6 solution was applied as an electrolyte to improve the thermal stability of Li-ion batteries. Methyl difluoroacetate is used in the inhibition of corrosion of aluminum cathode current collector for lithium ion cells.
General Description
The gas-phase reactions of Cl atoms with methyl difluoroacetate have been investigated at 296 ± 2K and atmospheric pressure of synthetic air.
