Abstract
IT IS PROPOSED TO EVALUATE NAFEO2 AND FEOCI AS POSITIVE ELECTRODES (CATHODES) FOR A MODERATE TEMPERATURE RECHARGEABLE NA BATTERY OF THE CONFIGURATION LIQUID NA/BETA"-A12O3/MOLTEN NAFEO2 NAALCL4, OR FEOCL THE ANTICIPATED OPERATING TEMPERATURE RANGE OF THE BATTERY IS 175 TO 200 DEGREES C. THESE OXIDE AND OXYCHLORIDE CATHODES ARE EXPECTED TO SHOW AN INSERTION OR INTERCALATION TYPE POSITIVE ELECTRODE REACTION AFFORDING VERY LONG CYCLE LIFE FOR THIS BATTERY. WHEN FULLY DEVELOPED, PRACTICAL NA BATTERIES HAVING ENERGY DENSITIES AS HIGH AS 200 WHR/KG ARE EXPECTED WITH THE USE OF THESE CATHODE MATERIALS. AN ADDED ATTRACTIVENESS OF THESE MATERIALS IS THAT THEY ARE INEXPENSIVE.
