What is a Lithium sulfide (Li₂S) ?

Lithium sulfide (Li₂S) is an inorganic compound composed of lithium ions (Li⁺) and sulfide ions (S²⁻). It typically exists as a white crystalline or powdery solid and reacts with water to form lithium hydroxide (LiOH) and hydrogen sulfide (H₂S). Lithium sulfide plays a significant role in the production of lithium batteries and is also used in synthetic chemistry. It is utilized as an electrolyte in lithium-ion batteries, a key component in energy storage and power supply. Additionally, lithium sulfide acts as a reducing agent in certain chemical reactions. Due to its high reactivity, proper handling and safety precautions are essential when working with lithium sulfide.
