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

we focus on novel battery material production. We are one of world-leading li-salt product companies. With rich understanding of the process, optimized synthesis technology, salt purification and dry process. And the main products are LiBF4(14283-07-9),LiBOB(244761-29-3),LiDFOB(409071-16-5) and the electrolyte research for li primary battery, li rechargeable battery, ultracapacitor ect.We have many engineers experienced in equipments, material synthesize, and process optimization.
