Molten Salt Battery
Molten salt batteries are a class of primary cell and secondary cell high-temperature electric battery that uses molten salts as an electrolyte. In most cases the salt used is a sodium salt and they are then often referred to as a liquid sodium battery. They offer both a high energy density through the proper selection of reactant pairs as well as a high power density by means of a high-conductivity molten salt electrolyte.
These types of batteries are used where high energy density and high power density are required. These features make rechargeable molten salt batteries a preferred energy storage to balance out environment-dependent power plants (solar, wind, etc.). Historically, thermal batteries have often been used in guided weapon systems such as surface-to-air-missiles. Rechargeable molten-salt batteries are a promising technology for powering electric vehicles. With operating temperatures of 400 °C (752 °F) to 700 °C (1,292 °F), they have problems of thermal management and safety, and they place stringent requirements on the rest of the battery components. Some newer designs, such as the ZEBRA battery, operate at a lower temperature range of 245 °C (473 °F) to 350 °C (662 °F).

Famous quotes containing the words molten and/or salt:
“And but for fancies, which aver
That all thy motions gently pass
Athwart a plane of molten glass,
I scarce could brook the strain and stir”
—Alfred Tennyson (1809–1892)
“In order for the wheel to turn, for life to be lived, impurities are needed, and the impurities of impurities in the soil, too, as is known, if it is to be fertile. Dissension, diversity, the grain of salt and mustard are needed: Fascism does not want them, forbids them, and that’s why you’re not a Fascist; it wants everybody to be the same, and you are not. But immaculate virtue does not exist either, or if it exists it is detestable.”
—Primo Levi (1919–1987)
