Abstract

Effect of fluoride additives was investigated in organic solvents containing LiCF₃SO₃ to prevent the corrosion of aluminum current collector for lithium ion batteries. LiClO₄ was also examined for comparison. Among examined LiBF₄, LiPF₆, LiAsF₆, LiSbF₆ and LiClO₄, LiBF₄ was the best additive to suppress the corrosion of aluminum because its oxidation potential is close to that of CF₃SO₃^- anion. Corrosion currents for aluminum in a complex fluoride- or LiClO₄-added solvents became smaller in the order, LiSbF₆ > LiAsF₆ > LiClO₄ > LiPF₆ > LiBF₄. Oxidation potential of ClO₄^- is nearly the same as that of CF₃SO₃^-. However, the corrosion currents were similar to or slightly larger than those observed in LiPF₆-added solvents. SEM images of electrochemically oxidized aluminum samples indicated that the level of corrosion well coincided with the observed corrosion currents. The corrosion mechanism of aluminum was also proposed.
