Lithium oxalyldifluoroborate (LiODFB,LiDFOB,LiFOB) LiBC2O4F2 143.77g/Mol Purities:>99.5% Moisture:<0.025% Battery grade Can use as SEI forming additive conductive salt replace LiPF6 fhigh performance lithium rechargeable batteries. With high temperature stability: decomposition temperature over 240 °C (TGA experiment); form more stable proposing SEI on cathode anode material; improve battery high temperature performance; effectively suppress Mn Fe dissolve from cathode material; Hygroscopic; Specially can replace LiPF6 as main salt use in EV/XEV batteries. The electrolyte shows best thermal stability lower SEI resistance with good low temperature performance As a novel conductive lithium salt, LiDFOB, which possess good film forming property high thermal stability. It shows several very interesting properties fits use in lithium-ion batteries including excellent Al-corrosion-protection properties, excellent cycling behaviof lithiated carbon anodes cathodes, no HF-evaluation upon hydrolysis, far better solubility when compared to LiBOB. Even only with LiDFOB solvents, battery can get good performance
