Preparation and Application of Lithium Tetrafluorooxalatophosphate
Lithium tetrafluorooxalatophosphate is mainly used as an additive for non-aqueous elec-trolytes such as lithium-ion batteries and lithium-ion capacitors or as a salt for new lithium-ion battery electrolytes,which can improve the thermal stability and hydrolytic stability of electrolytes.Compared with lithium hexafluorophosphate,lithium tetrafluorooxalatophosphate has better thermal stability and water resis-tance,and forms a more stable solid electrolyte interface film(CEI film)on the surface of the cathode mate-rial,which effectively improves the high-temperature cycling and high-temperature storage performance of the battery,so it has a wide range of applications in the field of high nickel and high voltage.This article provides an overview of the preparation and application of Lithium tetrafluorooxalatophosphate,which can be used as a reference for lithium-ion battery electrolytes and lithium-ion battery developers.
