Molten salt batteries are a type of battery system that uses molten salts as electrolytes and offer a high power density and high energy density with a long lifespan. At room temperature, the components of molten salt batteries are solid, due to which they can be stored in an inactive state for extended periods of time. When the molten salt batteries are activated, the electrolytes, cathodes, and anodes separate, and ionic exchange takes place that generates energy.
