Abstract Scope |
An attractive option for grid-scale energy storage, liquid metal batteries (LMB) display minimal degradation and high efficiencies due to the liquid state of the electrodes. Commercial LMBs require high operating temperatures (~600°C), increasing risk of corrosion and decreasing economic viability. The use of liquid Na and Hg electrodes that are molten at low temperatures may help to alleviate issues with current LMBs. This work focuses on improving the performance of a Na – Hg LMB with a solid-state NaSICON electrolyte that operates at 110°C. The interaction between the Hg electrode and NaSICON needs to be investigated to ensure long cycle life and high performance of the LMB. X-ray diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS) were used to characterize the structural, morphological, and chemical interaction between the Hg electrode and NaSICON. This work was supported by Nevada Gold Mines and NSF MRI award 2117820. |
