Abstract: The use of surface active agents as inhibitory additives to the electrolyte in wet electrolytic capacitors employing aluminum electrodes is described. Each molecule of the inhibiting amphiphilic substances contains a strongly inhibiting hydrophilic group attached to a hydrophobic group.

Abstract: Both the passivation of aluminum foil particularly for use as electrodes in wet electrolytic capacitors and the inhibition of the aluminum-water reaction within the completed capacitor are described. Pretreatment of etched aluminum foil includes the combined steps of immersion in a boiling aqueous solution containing Cr03 and H3PO4 followed by a 3-minute immersion in a boiling solution of controlled pH containing H2PO4 , SiO3 and CrO3. Inhibition of aluminum in a wet electrolytic capacitor is afforded by the addition of a concentration of at least one of the following inhibiting ions to the liquid electrolyte: phosphate, phosphite, periodate, arsenate, tungstate, silicate, vandadate, tellurate, tellurite, antimonate, arsenite, selenate, sulfite and germanate.
