Abstract

EC-DMC-DEC solutions comprising LiPF₃(CF₂CF₃)₃ (LiFAP), LiPF₆ and LiN(SO₂CF₂CF₃)₂ (LiBETI) were tested with graphite and LiMn₂O₄ electrodes. Cyclic voltammetry (CV, fast and slow scan rates), chronopotentiometry, impedance spectroscopy, surface sensitive FTIR and XPS were used for this study. It was found that the new salt LiFAP is a promising candidate for use in rechargeable Li-ion batteries. The thermal behavior of these electrolyte solutions was also studied using accelerating rate calorimetry (ARC). It was found that LiFAP solutions are more stable than LiPF₆ solutions while LiBETI solutions have the highest thermal stability.
