| Abstract Scope |
The coupling of renewable energy technologies (e.g., wind, solar, and nuclear) with large-scale stationary energy storage technologies such as liquid metal batteries (LMBs) has the potential to stabilize an electrical grid less reliant on carbon-based technologies. However, the energy produced from such systems must be cost competitive with current carbon-based energy. The Li(l)|LiF-LiCl-LiBr|Sb-Sn(l) LMB system may be utilized as a high-performance option for such applications by employing an antimony-tin (Sb-Sn) fusible alloy to lower the necessary operating temperature. However, lithium salts are significantly more expensive than other alkali or alkaline earth metal salts (e.g., KCl, SrCl2) making production less economically viable. Techniques such as coulometric titration at various current densities and electrochemical impedance spectroscopy are employed to observe changes in coulombic efficiency, current-overpotential relationships, and theoretical capacity as well as the effects of cation co-deposition as mixed cation molten salts are introduced to the Li-Sb-Sn system. |
