High energy density battery with trihydrocarbyl carbamate based electrolyte
Abstract
Abstract HIGH ENERGY DENSITY GALVANIC BATTERIES HAVING HIGH UTILIZATION OF ACTIVE ELECTRODE MATERIAL CAN BE PREPARED USING VOLTAIC CELLS HAVING AN ANODE OF ONE OF THE LIGHT METALS OF GROUP I-A OR II-A OF THE PERIODIC TABLE, A CATHODE OF IRON SULFIDE, COPPER, SULFIDE, NICKEL SULFIDE OR NICKEL FLUORIDE AND AN ELECTROLYTE COMPRISED OF TRIHYDROCARBYL CARBAMATE AS SOLVENT AND UP TO ABOUT 30% BY WEIGHT OF A CONDUCTIVE SALT, HAVING THE FORMULA MM''F6 WHERE M IS LI, NA OR K AND M'' IS P, AS OR SB, DISSOLVED THEREIN. OPTIONALLY UP TO ABOUT 40% BY WEIGHT OF THE SOLVENT CAN BE COMPRISED OF A SECONDARY SOLVENT, HAVING THE FORMULA R3O-(CH(R4)CH2-)NR3 IN WHICH R3 IS A C1 TO C3 ALKYL GROUP, R4 IS HYDROGEN OR A METHYL GROUP AND N IS 0-2, TO IMPROVE LOW TEMPERATURE PERFORMANCE OF THE BATTERY.
