Abstract:

THE ANTICIPATED RESULT OF THE PROPOSED PHASE I WORK IS THE DEVELOPMENT OF AN ELECTROLYTE FOR THE LITHIUM (LI)/SILVER VANADIUM OXIDE (SVO) SYSTEM THAT WOULD PROVIDE CELL PERFORMANCE AT -40 DEGREES CENTIGRADE AS DEMANDED BY EMERGENCY LOCATOR TRANSMITTERS (ELTS) AND EMERGENCY POSITIONINDICATING RADIO BEACONS (EPIRBS). THE LI/SVO CHEMISTRY WASCHOSEN DUE TO ITS HIGH VOLUMETRIC ENERGY DENSITY, GOOD HIGH RATE PERFORMANCE, LOW SELF-DISCHARGE, STATE OF CHARGE INDICATION, EXCELLENT SAFETY CHARACTERISTICS, AND ABUSE RESISTANCE. IMPLEMENTATION OF THIS CHEMISTRY WOULD PROVIDE CELLS CONTAINING NON-NOXIOUS ELECTROLYTES WITH THE PERFORMANCE AND SAFETY CHARACTERISTICS DESIRED FOR THE APPLICATION. PHASE II WOULD INVOLVE THE DEVELOPMENT OF MODERATELY PRICED SPIRALLY WOUND CELLS SUITABLE FOR ASSEMBLYINTO BATTERY PACKS FOR ELT AND EPIRB USE. POTENTIAL COMMERCIAL APPLICATIONS INCLUDE MILITARY AND SPACE APPLICATIONS, BUOYS, WEAPONS SYSTEMS, AND OTHER APPLICATIONSREQUIRING HIGH RATES AT WIDE TEMPERATURE RANGES. CURRENT STATE-OF-THE-ART PRIMARY BATTERY TECHNOLOGY HAS ACHIEVED ENERGY DENSITIES AS HIGH AS 1 WH/CC, OR 500 WH/KG. APPLICATIONS IN SPACE WILL REQUIRE EVEN HIGHER ENERGY DENSITIES, AND NOVEL BATTERY CONCEPTS ARE ONE APPROACH TO IMPROVING THE VOLUMETRIC AND GRAVIMETRIC ENERGY EFFICIENCY OF SPACE POWER. THE LITHIUM BROMINE FLUORINE (LI/BRF3) COUPLE IS BEING INVESTIGATED AS A POSSIBLE NEW HIGH ENERGY DENSITY SYSTEM. THIS SYSTEM HAS PREVIOUSLY DEMONSTRATED AS (EMF) OF 5.12 V. IN ADDITION, BRF3 HAS SEVERAL DESIRABLE PHYSICAL PROPERTIES. IF FEASIBILITY IS PROVED OF PACKAGING THIS SYSTEM IN CONFIGURATIONS SIMILAR TO CURRENT LITHIUM/OXYHALIDE CELLS, ENERGY DENSITIES AS HIGH AS 2.8 WH/CC, OR 1500 WH/KG COULD BE CONCEIVABLE ACHIEVED. IN DETERMINING THE FEASIBILITY OF DEVELOPING A LI/BRF3 PRODUCT, THE EXPERIMENTATION IS FOCUSSING ON MATERIALS COMPATABILITY AND GATHERING INFORMATION AS TO THE REALISTIC ENERGY DENSITIES IN PRACTICAL PRIMARY CELL PROTOTYPE CONFIGURATIONS. DRASTIC IMPROVEMENTS IN ENERGY DENSITY ARE DEEMED NECESSARY IN MILITARY SPACE APPLICATIONS. SUCCESSFUL DEVELOPMENT OF LIBRF3 THE OBJECTIVE OF THIS PROGRAM IS TO PREPARE USEFUL LENGTHS OF A HIGH TEMPERATURE SUPERCONDUCTING WIRE AND TO DEMONSTRATE THAT THE WIRE IS A PHYSICALLY STABLE SUPERCONDUCTOR WITH HIGH CURRENT CARRYING CAPABILITY, SUITABLE FOR POWER TRANSMISSION, CONDITIONING, AND STORAGE SYSTEMS. THE WIRE IS BEING CHARACTERIZED FOR: RESISTIVITY, AS A FUNCTION OF TEMPERATURE AND CURRENT DENSITY; PHYSICAL STABILITY; RESPONSE IN AN RLC RESONANT CIRCUIT; MEISSNER EFFECT; AND THE EFFECT AN APPLIED MAGNETIC FIELD HAS ON CRITICAL CURRENT DENSITY. THE GROSS PHYSICAL CHARACTERISTICS OF THE WIRE ARE BEING DETERMINED BY A SCANNING ELECTRON MICROSCOPE. AUGER PROFILE ANALYSIS IS USED TO DETERMINE THE WIRE CHEMISTRY. THE EFFECTS OF MOISTURE, REPEATED TEMPERATURE CYCLES, AND REOXIDATION ARE ALSO BEING EVALUATED. THE MANUFACTURING PROCESS, IF SUCCESSFUL, WILL HAVE IMMEDIATE APPLICATION IN PROVIDING COMMERCIAL SUPERCONDUCTING WIRE FOR THE FABRICATION OF ADVANCED HIGH-FIELD MAGNETS AND SOLENOIDS, ELECTRIC MOTOR WINDINGS, SUPERCONDUCTING ROTORS IN ELECTRIC POWER GENERATORS, TRANSFORMERS, INDUCTION ENERGY STORAGE SYSTEMS, AND SQUIDS.
