MSE PRO™ 99.5% Sodium Difluorophosphate (NaPO2F2) Electrolyte Additive for Sodium Ion Battery

Sodium ion battery (SIB) is a type of rechargeable battery analogous to the lithium-ion battery but using sodium ions (Na+) as the charge carriers. Sodium-ion battery can be the best alternative to lithium-ion batteries, owing to their similar electrochemistry, non-toxicity, elemental-abundance and the low-cost of sodium.

Sodium Difluorophosphate (NaPO2F2, NaDFP) is a white powder used for SIB electrolyte additive. Difluorophosphate (PO2F2−, DFP) electrolyte additives is widely used in lithium and potassium-ion batteries to improves their lifetime. The modification of DFP anions can effectively remit the electrode/electrolyte interfacial reaction and relieve the increase of internal resistance during cycling. Therefore, NaDFP is also explored as an additive for optimizing SIB performance.
