AN AQUEOUS ELECTROLYTE FOR ALUMINUM-ANODE CAPACITORS IS COMPRISED MAINLY OF AN ACID SUCH AS MALEIC ACID, A MALEATE OF AN ALIPHATIC AMINE SUCH AS TRIETHYLAMINE, ORTHOPHOPHORIC ACID, A SOLVENT SUCH AS DIMETHYLFORMAMIDE, AND OPTIONALLY A SMALL QUANTITY OF BORIC ACID. SUCH AN ELECTROLYTE OFFERS HIGH ELECTRICAL CONDUCTIVITY AND FOR ALL PRACTICAL PURPOSES A SUFFICIENTLY HIGH MAXIMUM BUILDUP VOLTAGE, THE CAPACITORS WHICH UTILIZE SUCH ELECTROLYTE BEING USABLE OVER A WIDE TEMPERATURE RANGE. |
