Abstract
STORAGE OF ELECTRICAL ENERGY AT A SUFFICIENTLY HIGH DENSITY, IN A SMALL ENOUGH VOLUME AND WITH HIGH ENOUGH EFFICIENCY OF EXTRACTION IS INCRESINGLY BECOMING A SIGNIFICANT PROBLEM. CONVENTIONAL CAPACITIVE DEVICES (E.G., ELECTROLYTIC CAPACITORS) FALL SHORT OF PROVIDING THE VOLUMETRIC EFFICIENCY REQUIRED TO SUPPORT NEW TECHNOLOGIES FOR COMPLEX FUZE REQUIREMENTS. WE PROPOSE TO DEVELOP AN ENERGY STORAGE DEVICE WHICH COMBINES THE BEST FEATURES OF HIGH ENERGY DENSITY RECHARGE-ABLE LITIUM NON-AQUEOUS BATTERIES WITH THE HIGH DISCHARGE RATE CAPABILITY OF CAPACITORS TO CREATE AN INNOVATIVE RECHARGEABLE ENERGY STORAGE DEVICE WITH BOTH GLAVANIC AND CAPACITIVE PROPERTIES. SPECIFICALLY, THE RECENT DEVELOPMENT OF EXTRAORDINARILY HIGH SURFACE AREA (1500 M2/G) ACTIVE CARBON FIBER (ACF) NON-WOVEN CLOTH, ORIGINALLY INTENDED FOR AIR PURIFICATION SYSTEMS, HAS YIELDED A NOVEL BATTERY PLATE MATERIAL. PLACEMENT OF A SUITABLY DOPED ACF ELECTRODE OPPOSITE A HIGH ENERGY DENSITY LITHIUM ANODE IN A HIGH CONDUCTIVITY NON-AQUEOUS ELECTROLYTE CREATES A DEVICE WITH CAPACITY FROM BOTH THE DOUBLE LAYER CAPACITANCE AND GALVANIC CONTRIBUTIONS. ENERGY DENSITIES GREATER THAN 500 J/# ARE EXPECTED AS WELL AS ULTRAFAST RESPONSE TIME. IMPACT SURVIVABLE BIPOLAR ELECTRODES ARE DESCRIBED FOR EVENTUAL USE IN 1500 V PILE.
