 Research on lithium-sulphur and lithium-oxygen batteries has increased significantly, in the past decade due to their high theoretical energy density and abundance of sulfur and oxygen, but progress towards practical device development is hindered by fundamental key issues. Sodium-based battery systems are also being explored due to their natural abundance and potential for low-cost components, with room-temperature Na-slash-S8 and Na-slash-NICL-2 batteries already commercialized. The substitution of lithium for sodium has a significant impact on the overall properties of the cell reaction, including ion transport, phase stability, electrode potential, energy density, etc., and some initial reports on room-temperature Na-slash-S8 and Na-slash-O2 cells show exciting differences compared to Li-slash-S8 and Li-slash-O2 systems.
