Abstract : The objective of this study was to investigate a number of commercial ceramic materials as possible anode-cathode separator materials for a lithium-chlorine battery. It had been demonstrated that common insulating materials, such as those based on Al2O3, SiO2, or organic materials, would fail due to high operating temperature (450C), corrosive environment experienced by the separator, or solubility in the molten salt electrolyte. Several promising materials were investigated in lithium-chlorine cells for periods of up to 284 hours during which the cell was continuously charge-discharge cycled. The materials showing the least corrosion at the conclusion of this investigation were binder-free BN, hot pressed AlN, and Hot pressed Si3N4.
