Abstract: High capacity alkali metal/oxygen batteries, e.g. Li/O 2 batteries, employing molten salt electrolytes comprising alkali metal cations and nitrate anions are disclosed. Batteries of the present invention operate at an intermediate temperature ranging from 80° C to 250° C. Molten alkali metal nitrate electrolytes employed in O 2 electrodes within this temperature range provide alkali metal/oxygen batteries having significantly improved efficiency and rechargeability compared to prior art systems.

Abstract: High energy rechargeable batteries employing catalyzed molten nitrate positive electrodes and alkali metal negative electrodes are disclosed. Novel and advantageous aspects of the present invention are enabled by the provision catalytically active materials that support the reversible formation of NO 3 - from O 2 - and N0 2 - during battery charging. Such catalytically active materials allow highly efficient cycling and selectively eliminate irreversible side reactions that occur when cycling without such catalysts.
