Y. Qin, Z. Chen, J. Liu, K. Amine, Electrochem. Solid-State Lett. 2010, 13, A11-A14. Lithium tetrafluoro oxalato phosphate as electrolyte additive for lithium-ion cells. 

In 2000, Central Glass Co, Ltd. discovered lithium salts containing a structure of oxalic acid, such as lithium tetrafluoro(oxalato)phosphate (175) and lithium difluorobis(oxalato)phosphate (176) [159],... 

An analogue of LiDFOB is lithium tetrafluoro(oxalato)phosphate (LiPF4C204, or LiFOP), in which phosphorous is the coordination center. This salt was initially synthesized by Prof. Brett Lucht s group at the University of Rhode Island. It has... 

Although having P-F bonds in the strucmre, lithium tetrafluoro(oxalato)phos-phate (LiFOP, Fig. 14) has much better thermal stability than LiPFs. Another thermally stable phosphorous-based salt is a tri-chelated salt, lithium tris [l,2-benzenediolato(2)-0,0 ]phosphate (LTBP, Fig. 16) [43], but it cannot be used in the Li-ion battery because of its insufficient electrochemical window related to the less stable phenol ligands.
