Overview

Lithium difluorophosphate (LiDFP) is a high-performance additive for lithium-ion batteries. LiDFP is a white powder that is soluble in acetone and dimethoxyethane and slightly soluble (0.4g/100g solvent) in both diethyl carbonate and 1:1 v/v mixtures of dimethylcarbonate and propylene carbonate. Our LiDFP is designed with high-purity and low trace impurities of moisture and acid

Application：

Lithium difluorophosphate is a multi-functional additive for high voltage lithium-ion batteries and is often added to lithium hexafluorophosphate (LiPF6)-based electrolytes in carbonate solvents. For example, a recent study showed that a 1 wt% addition of LiDFP to the LiPF6-carbonate electrolyte in a NMC-graphite cell significantly increased capacity retention (97%) after 200 cycles, compared to the same cells without the additive (only 77% capacity retention.)[1] LiDFP has been shown to perform well with nickel-rich cathode materials[2] because it generates a more uniform, extremely stable, and lower resistance solid-electrolyte interphase (SEI) on the cathode surface. This passivation film not only suppresses the subsequent decomposition of the electrolyte, but also prevents the dissolution of transition metal ions from NMC particles, resulting in improved cyclic stability and discharge capacity. In addition, research suggests that LiDPF additive also helps to form a stable and ionically conductive SEI passivation film on lithium metal anodes.[3] Our LiDFP, with high-purity and low moisture and acid impurities, is suitable for research on increasing the energy density and longer cycling performance in lithium-ion batteries and lithium-metal batteries.
