IMPROVED LITHIUM/THIONYL CHLORIDE CELLS USING NEW ELECTROLYTE SALTS

THE OBJECTIVE OF THE PROPOSED RESEARCH IS TO LIMIT VOLTAGE DELAY, ANODE CORROSION DURING INTERMITTENT USAGE AND TO INCREASE THE CURRENT CAPABILITY AND CAPACITY OF LI/SOCL(2) CELLS THROUGH THE USE OF NEW ELECTROLYTE SALTS. THE PRINCIPLES USED WILL BE THOSE WHICH HAVE SUCCEEDED IN THE PAST, NAMELY, BY LIMITING THE CONCENTRATION OF THE ELECTROLYTE SALT AND BY USING THE LITHIUM SALTS OF LARGE ANIONS WHICH EITHER CANNOT EXCHANGE WITH THE LITHIUM CHLORIDE SOLID ELECTROLYTE INTERPHASE, OR HAVE REDUCED ABILITY TO EXCHANGE. HOWEVER, THE NEW SALTS WILL NOT BE SUBJECT TO OXIDATION BY THE RELEVENT AND WILL NOT BE EXPENSIVE. THE WORK WILL INCLUDE THE SYNTHESIS AND ANALYSIS OF THE NEW SALTS, MEASUREMENTS OF SOLUBILITIES AND PRELIMINARY EVALUATION OF CAPACITY, RATE CAPABILITY, AND VOLTAGE DELAY, USING AA CELLS, COMPARING THE NEW ELECTROLYTES WITH 1.8M LIALCL4/SOCL(2) FRESH AND AFTER STORAGE AT 71 DEG C FOR ONE MONTH.
