The thermal stability order by DeltaDeltaE (anion) is PF4(CF3)2->PF5(CF3)->PF3(CF3)3->PF6-. The ion-dissociation ability order by DeltaDeltaE (Li salts) is LiPF3(CF3)3>LiPF4(CF3)2>LiPF5(CF3)>LiPF6. The conductivity of electrolyte solution with LiPF4(CF3)2 (3.9 mS/cm) was a little lower than that of LiPF6 (4.4 mS/cm) in 0.1 mol/l Li salt/PC:DME electrolyte, while the oxidation potential of LiPF4(CF3)2 in PC was higher than that of LiPF6. The LiPF4(CF3)2-cell showed better cycle characteristics than LiPF6-cell.
