A salt that is normally liquid even at standard temperature and pressure is usually called a room temperature ionic liquid, and so technically molten salts are a class of ionic liquids.
Experimental salts using lithium can be formed that have a melting point of 116 °C while still having a heat capacity of 1.54 J/(g K).[5] Salts may cost $1,000 per ton, and a typical plant may use 30,000 tons of salt.[6]
