Abstract
Abstract A sealed primary sodium-halogen battery is disclosed which has a high temperature sodium and halogen resistant closed glass envelope surrounding a casing of sodium ion-conductive material with one open end and sealed to the casing adjacent its open end. An anode is positioned preferably in the casing while a cathode of a halogen in conductive material is positioned preferably within the glass envelope between the exterior surface of the casing and the glass envelope and in contact with the casing.
