This work should be considered a first attempt at the construction of a high temperature lithium metal-air battery using a solid oxide fuel cell type architecture on the air electrode. We showed that an open circuit voltage consistent with the Li-O2 reaction can be obtained, and the cell shows a significant amount of discharge capacity. Unfortunately, we found that if the cell completely discharged, the lithium could not be re-deposited, possibly due to (electro)chemical side reactions with the LLZO tube used in the experiment. In the future, further analysis of the discharge products is needed to confirm the presence of Li2O in the molten salt. In addition, it is clear from the color changes in the LLZO tube that significant (electro)chemical reactions are taking place. Future work should seek to design solid electrolyte materials which are either stable to lithium metal at high temperatures, or are coated with a thin layer of a lithium metal stable material. The challenges of operating a lithium metal battery at such high temperatures are significant, but provide an interesting area of further research and may be useful for other fields such as lithium metal electrodeposition.
