What Is Lithium Sulfate?
Lithium sulfate is an inorganic compound with the chemical formula Li2SO4, formed by the reaction of sulfuric acid with lithium or its compounds such as lithium hydroxide or lithium oxide, resulting in lithium sulfate and water.
It appears as a white, crystalline powder and is soluble in water but almost insoluble in ethanol. Lithium sulfate is hygroscopic and should be stored in a dry environment to prevent moisture absorption.
This nonflammable compound can produce corrosive or toxic fumes when heated.
Uses of Lithium Sulfate
Lithium sulfate is used as an electrode material in aqueous lithium-ion batteries, utilizing its solubility in water. These batteries are under research and development for being safer alternatives to conventional lithium-ion batteries, minimizing risks of ignition or explosion. Additionally, lithium sulfate is used as a hardening accelerator in cement, promoting faster hydration and solidification.
