Product Details:

Lithium difluoro(bisoxalato)phosphate (LiDFBOP or LiDFBP) is introduced as a novel lithium-salt-type electrolyte additive for lithium-ion batteries. The research reveals that LiDFBOP is oxidized to form a uniform and electrochemically stable solid electrolyte interphase (SEI) on electrode material. Fluorinated SEI rich in LiF and Li_xPO_yF_z species can be yielded, which can further improve the stability and ionic conductivity of SEI for fast Li⁺ transportation. It is widely used to improve the stability and safety of nickel-rich cathode based lithium ion battery and lithium metal batteries.
