Abstract

A novel salt for lithium ion battery electrolytes, lithium tetrafluorooxalatophosphate (LiPF4(C2O4)), has been prepared and investigated. The conductivity, electrochemical stability, and cycling performance of 1.0 M LiPF4(C2O4) in 1:1:1 ethylene carbonate:dimethyl carbonate:diethyl carbonate are comparable to the industry standard LiPF6 electrolyte. However, the LiPF 4(C2O4) electrolyte has much better thermal stability. LiPF4(C2O4) electrolytes are a promising alternative for lithium ion batteries. ©The Electrochemical Society.
