摘要: We evaluated (1) thermal and electrochemical stability (2) ion-dissociation ability of PF 6-n (CF 3 ) n anions by computational method. The order ΔΔE (anion) is 4 - 2 > 5 6 . (Li salts) LiPF conductivity electrolyte solution with (3.9 mS/cm) was a little lower than that (4.4 in 0.1 mol/l Li salt/PC:DME electrolyte, while the oxidation potential PC higher -cell showed better cycle characteristics -cell.
