Abstract
A rotating disk electrode technique was applied to the detection of the kno wn impurities in a nonaqueous electrolyte solution used for electrochemical capacitors. Propylene glycol and fluoride ion, which are both hydrolysis p roducts of the nonaqueous electrolyte solution composed of propylene carbon ate solvent and triethylmethylammonium tetrafluoroborate salt, were quantit atively detected by a glassy carbon based rotating disk electrode in the co ncentration range of 10 to 100 ppm, where normal linear sweep voltammetry c annot be applied.
