Abstract
Briefly stated, the present invention is directed to a liquid electrolyte for an electrolytic capacitor, as well as an electrolytic capacitor made therewith. The electrolyte includes a liquid portion comprising an aprotic solvent at a level of at least about 90 percent by weight of the liquid portion. The electrolyte also includes ammonium borodisalicylate at a level of at least about 2 percent by weight of the total electrolyte. In addition to the above-described electrolyte, the electrolytic capacitor includes a pair of electrodes, at least one of which is composed of a film-forming metal.
