一般說明
The gas-phase reactions of Cl atoms with methyl difluoroacetate have been investigated at 296 ± 2K and atmospheric pressure of synthetic air.
應用
Methyl difluoroacetate has been used:
- to compose the electrolyte for Lithium ion cells, also showed good inhibition of aluminum cathode current collector corrosion
- as electrolyte solvent for improvement of thermal stability in lithium-ion batteries
