Increasing demand for renewable energy requires a shift to microgrids with energy storage systems. Liquid metal-air flow batteries have theoretically high energy densities and long life cycles, satisfying microgrid requirements. A proof of concept for this battery was established with a gallium-air electrochemical cell to determine performance and limiting factors. It was determined that the gallium-air chemistry was feasible, achieving a flat discharge profile for over 4.7 hours on average. Electrolyte carbonation, separator drying, and oxide layer formation hindered performance.
