MSE PRO™ Lithium Difluorophosphate (LiDFP), >99%

Lithium Difluorophosphate (LiDFP) is an off-white electrolyte additive. Its most common uses include being used as an electrolyte material in rechargeable batteries. It can reduce battery self-discharge, reduce the volume of lithium hexafluorophosphate, improve the battery high and low temperature performance to improve the cycling efficiency and capacity retention of cells and improve power capability.
