Description
Lithium Difluorophosphate Product Overview
Lithium difluorophosphate (LiPO2F2) is a white crystalline powder that dissolves only moderately in carbonate solvents. It forms thin, stable protective layers on both the cathode and the anode.
In addition, electrolyte producers add it at about 0.5–1.5% to electrolytes based on Lithium Hexafluorophosphate, Ethylene Carbonate and linear carbonates, often together with Vinylene Carbonate and Fluoroethylene Carbonate (FEC). It lowers cell resistance, especially at low temperatures, and reduces gas formation and capacity loss in high-voltage and fast-charging cells for electric vehicles.
Notably, related battery salts in our range include Lithium Bis(fluorosulfonyl)imide (LiFSI) and LiTFSI (Lithium Bis(trifluoromethanesulfonyl)imide).
Key Applications of Lithium Difluorophosphate
Typical uses include, for example:
🚗 EV Cells
Fast charging and power.
❄️ Low-Temperature Performance
Lower cell resistance.
⚡ High-Voltage Cells
Less gassing.
🔬 Battery Research
Electrolyte development.
