Abstract Scope |
Molten sodium batteries offer a unique option towards development of a large-scale energy storage device. Sodium (Na) offers many advantages: largely abundant, low melting point (~98°C), and above average electrochemical properties. Current research efforts are focused on identifying an electrolyte and a counter electrode to pair with molten sodium that can operate at moderately low temperatures (<150°C). This presentation will focus on the performance of a novel Na – mercury (Hg) battery that operates with a solid – state NaSICON electrolyte. More specifically, the effect of temperature on the electrochemical properties of this battery system will be explored. This includes cell reversibility, energy efficiency, and discharge capacity at a range of temperatures between 110°C to 150°C. Optimization of a molten sodium battery system that operates at a low temperature will allow for a long-term, feasible large-scale energy solution.
