RECHARGEABLE BATTERIES EMPLOYING CATALYZED MOLTEN NITRATE POSITIVE ELECTRODES

摘要

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 NO3 - from O 2 -and N02 -during battery charging. Such catalytically active materials allow highly efficient cycling and selectively eliminate irreversible side reactions that occur when cycling without such catalysts.
