Beschreibung
Zusammenfassung:	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. La présente invention concerne des batteries rechargeables haute puissance faisant intervenir des électrodes positives catalysées à base de nitrate fondu et des électrodes négatives à base de métal alcalin. Les aspects novateurs et avantageux de la présente invention résultent de l'utilisation de matériaux catalytiquement actifs qui supportent la formation réversible de NO3 - à partir de O 2 - et de NO2 - pendant le chargement de la batterie. De tels matériaux catalytiquement actifs offrent une formation de cycle très efficace et éliminent de manière sélective les réactions secondaires irréversibles qui surviennent lors d'une formation de cycle sans de tels catalyseurs.
