Lithium Difluorophosphate, LiDFP

CAS Number: 24389-25-1

Lithium difluorophosphate (often simply refer to as LiDFP), appears to be white powder, with its chemical formula LiPO2F2, molecular weight 107.91. Its melting point is 340°C (644°F). It shows acidity when exposed to the air and absorbs moisture.

It is often used in the field of lithium-ion batteries, as an electrolyte additive, it can improve the cycle performance and high-temperature storage performance of the battery. It helps to improve the battery's high and low temperature performance, reduce battery self-discharge, and notably reduce the volume of lithium hexafluorophosphate in use.
