Titanium disulfide is the lightest and cheapest of the Group IV chalcogenides, and it has the highest energy density of any layered battery cathode material. The intercalation of lithium ions into the layered structure is also reversible, making it possible for batteries to be recharged many times.

It is a semimetal in bulk form with a small overlap of the conduction and valence bands, becoming a semiconductor under strain or pressure. It is also a fullerene precursor, and its crystal structure can be modified to form spherical structures with diameters of up to 80 nm.

TiS2 is moderately water and acid soluble. It can be dispersed using suspended or coated nanoparticles and deposited on substrates such as sputtering targets and evaporation materials for thin films and solar cells.

This product was previously sold under the Alfa Aesar brand name. Documentation and labeling may refer to the legacy brand name.

Safety Data Sheet (SDS):

Titanium disulfide is a yellow to gray powder with an unpleasant odor and is used as a solid lubricant. It can cause irritation to the eyes, nose, and throat when inhaled or ingested. It reacts with acids to generate hydrogen sulfide, which is toxic and flammable. It decomposes in air to form irritating, corrosive, and/or toxic gases. It is a fire hazard and will ignite upon contact with water or steam, generating hydrogen sulfide. Exposure to fire or splashes of this chemical can result in severe burns.
