Physical and chemical state and use of titanium disulfide

Overview of titanium sulfide TiS2 powder

Titanium disulfideis an inorganic compound with the molecular formula TiS2. Brass flake crystals with metallic luster. The density is 3.22 g/mL. Stable at room temperature, stable to water, dilute sulfuric acid and hydrochloric acid, but nitric acid and concentrated sulfuric acid will decompose into sulfur. Lithium can be inserted between the titanium disulfide layers, and the composition of the compound LiTiS2 forming the inner layer changes continuously between x=0 and 1, which is an ideal non-stoichiometric compound. Titanium disulfide is a yellow or gray powder with an unpleasant odor and is used as a solid lubricant. Contact with this substance may burn skin, eyes and mucous membranes. May be toxic if swallowed, inhaled or absorbed through the skin.

Physical and chemical state and use of titanium disulfide

Titanium disulfide TiS2 powder has a layered structure, and each layered structure is composed of a sulfur-titanium-sulfur intermediate layer connected by weak van der Waals forces. Crystals can be grown by heating titanium wires in sulfur vapor, or synthesized by the reaction of titanium tetrachloride and hydrogen sulfide. Lithium can be inserted between the titanium disulfide layers, and the composition of the compound LiTiS2 forming the inner layer changes continuously between x=0 and 1, which is an ideal non-stoichiometric compound.

Titanium disulfide is an inorganic compound with the molecular formula TiS2. The stoichiometric unit ME2.TiS2 is a group of highly conductive golden yellow solids belonging to transition metal halogens, used as a positive electrode material for rechargeable batteries.

Titanium sulfide TiS2 powder application

Titanium sulfide TiS2 powder is mainly used in lithium batteries, targets, scientific research, etc.

In 1973, the prospect of using titanium disulfide as a positive electrode material for rechargeable batteries was proposed. Group IV and Group V halogen compounds have attracted attention due to their high conductivity. The battery originally described uses a lithium anode and a titanium disulfide cathode. The battery has high energy density, the diffusion process of lithium ions to the titanium disulfide anode is reversible, and the battery can be recharged.

Titanium disulfide TiS2 powder was chosen because it is the lightest and cheapest chalcogenide.

Lithium ions diffuse the fastest in titanium disulfide.

The main problem is the degradation of the cathode after repeated use. This reversible insertion process allows the battery to be charged. In addition, among all the layered dihalides IV and V, titanium disulfide is the lightest and least expensive.

In the 1990s, other cathode materials (manganese oxide and cobalt oxide) in most rechargeable batteries replaced titanium disulfide.

Using TiS2 cathodes in solid-state lithium batteries Most lithium-ion batteries use liquid electrolytes, which may pose a safety hazard due to their flammability. Many different solid electrolytes have been proposed to replace these harmful liquid electrolytes.

For most solid-state batteries, higher interface resistance reduces the reversibility of the insertion process and shortens the service life. For TIS2, these bad interface effects are no longer a problem. The power density of all solid-state lithium batteries is 1000 W/kg, and the maximum power density of 50 cycles is 1500 W/kg. In addition, the average capacity of the battery drops by less than 10% in 50 cycles. Although titanium disulfide has high conductivity, high energy density and high power, its discharge voltage is relatively low compared with other lithium batteries with high reduction potential cathodes.
