Battery grade

Can use as SEI forming additive or conductive salt replace LiPF6 for high performance lithium rechargeable batteries. With high temperature stability: decomposition temperature over 240 °C (TGA experiment); form more stable and proposing SEI on cathode and anode material; improve battery high temperature performance; effectively suppress Mn and Fe dissolve from cathode material; Hygroscopic;

Specially can replace LiPF6 as main salt use in EV/XEV batteries. The electrolyte shows best thermal stability and lower SEI resistance with good low temperature performance

As a novel conductive lithium salt, LiDFOB, which possess good film forming property and high thermal stability. It shows several very interesting properties for its use in lithium-ion batteries including excellent Al-corrosion-protection properties, excellent cycling behavior of lithiated carbon anodes and cathodes, no HF-evaluation upon hydrolysis, and far better solubility when compared to LiBOB. Even only with LiDFOB and solvents, battery can get good performance
