The effect of cation species on the anodic oxidation of organic solvent electrolytes

The anodic stability of a series of electrolytes consisting of propylene carbonate (PC) solvent and BF₄^- anion was shown to be partially influenced by cation species. A lithium cation lowered the anodic stability of electrolytes, particularly when the content of the cation was 1 mol dm^-3 or higher. It was considered that lithium cation had the high ability to coordinate anion species that provided the lower anodic stability. When the interaction between cation and anion was small enough, the higher anodic stability of BF₄^- anion was observed.
