Besides that, the use of molten salts as thermal energy storage materials has been the usual procedure in the concentrated solar power field of work .

Less expensive than lithium-ion battery technology, the new architecture uses aluminum and sulfur as its two electrode materials with a molten salt electrolyte in between.
That solution is the "electrolyte," and in PNNL''s battery, it''s made of molten salt. The salt is solid at room temperature, but liquid (or molten) at high temperatures. Because the charged particles in a molten salt battery can only move when the salt is liquid, the battery only works at high temperatures, about 350 degrees Fahrenheit.
Due to these properties, LMP molten salts could be excellent thermal storage media and heat transfer liquids in solar power plant systems. Current molten salt heat transfer fluid and thermal storage media are a mixture of 60% NaNO 3 and 40% KNO 3 [13]. The liquid temperature range is 220-600 °C.
