Lithium sulfide has been considered for use in lithium-sulfur batteries.

Lithium-sulfur batteries have been used on the longest and highest solar-powered flight.

Examples include lithium-sulfur batteries and explosives.

Lithium-sulfur batteries may succeed lithium-ion cells because of their higher energy density and reduced cost from the use of sulfur.

The lithium-sulfur battery (Li-S battery) is a rechargeable battery, notable for its high energy density.

The sodium-sulfur battery and the lithium-sulfur battery require high temperatures to maintain liquid polysulfide and Na-conductive membranes that are unreactive toward sodium, sulfur, and sodium sulfide.

Reactive wastes include lithium-sulfur batteries and explosives that can cause explosions, toxic fumes, or gases and toxic wastes that are harmful to human health or environment when inhaled or ingested or disposed.
