Abstract:

The faradaic and non-faradaic reactivity of lithium in the thionyl chloride battery system has been studied using AES, XPS, and SEMEDAX. The passivating film has been characterized as lithium chloride and found to contain substantial quantities of aluminum and sulfur. XPS results show definitely that in battery discharged lithium sulfur occluded within the passive film is present in multiple oxidation states, including sulfide. The reactivity of the lithium metal surface with O2, CO2, CO, and N2 was studied. The black spots were synthesized and analyzed as a lithium oxynitride. A model for ion transport across the passivating lithium chloride film was postulated and its implications discussed. The current interrupt method was tested on a model system. An AD interface and associated software was developed to enable rapid, accurate data acquisition.
