Overview of titanium sulfide TiS2 powder
Titanium disulfide is an inorganic compound with the molecular formula TiS2. Brass scaly 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 inner layer-forming compound LiTiS2 varies 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 cause burns to skin, eyes and mucous membranes. May be toxic if swallowed, inhaled or absorbed through skin.
Titanium disulfide is prepared by reacting the elements at around 500 °C.
Ti + 2 S → TiS2
It can be synthesized more easily from titanium tetrachloride, but the purity of this product is usually lower than that obtained from the element.
TiCl4 + 2 H2S → TiS2 + 4 HCl
This route has been applied to the formation of TiS2 thin films by chemical vapor deposition. Instead of hydrogen sulfide, mercaptans and organic disulfides can be used.
Various other titanium sulfides are known.
Titanium sulfide TiS2 powder application
Titanium sulfide TiS2 powder is mainly used for lithium batteries, targets, scientific research, etc.
In 1973, the prospect of using titanium disulfide as a cathode material for rechargeable batteries was proposed. Group IV and Group V halogen compounds have attracted attention due to their high electrical conductivity. The battery originally described used a lithium anode and a titanium disulfide cathode. The battery has high energy density, and the diffusion process of lithium ions to the titanium disulfide positive electrode is reversible and rechargeable.
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 recharge. Furthermore, among all the layered dihalides IV and V, titanium disulfide is the lightest and cheapest.
In the 1990s, titanium disulfide was replaced by other cathode materials (manganese oxide and cobalt oxide) in most rechargeable batteries.
Use of TiS2 Cathode in Solid-State Lithium Batteries Most Li-ion batteries use liquid electrolytes, which may pose safety hazards due to their flammability. Many different solid electrolytes have been proposed to replace these detrimental liquid electrolytes.
For most solid-state batteries, higher interfacial resistance reduces the reversibility of the insertion process and shortens the lifetime. For TIS2, these poor interface effects are no longer a problem. The power density of the all-solid-state lithium battery is 1000 W/kg, and the maximum power density for 50 cycles is 1500 W/kg. In addition, the average capacity of the battery dropped by less than 10% in 50 cycles. Although titanium disulfide has high electrical conductivity, high energy density, and high power, its discharge voltage is relatively low compared to other lithium batteries with high reduction potential cathodes.

According to Reuters, U.S. Treasury officials said they would discuss with G7 leaders pricing caps and tariffs on Russian oil as an alternative to the embargo, which would keep the market supplied, limit price spikes, and reduce Russian revenues.
The EU foreign ministers' meeting was held in Brussels. The meeting failed to agree on the sixth round of sanctions, including an oil embargo on Russia, because of objections from Hungary.
EU High Representative for Foreign Affairs and Security Policy said at a press conference after the meeting, that the meeting failed to reach an agreement on the final adoption of the sixth round of sanctions, the permanent representatives of member states to the EU will continue to discuss. The foreign ministers faced similar difficulties trying to reach an agreement on an oil ban. He said Hungary's position was based on economic rather than political concerns.
Hungary is highly dependent on Russia for energy, getting more than 60 percent of its oil and 85 percent of its natural gas from Russia.
A few days ago, the European Commission submitted the sixth round of proposed sanctions against Russia, including a total ban on Russian oil imports by the end of this year. Hungary immediately objected and said it wanted substantial compensation from the EU to offset its loss from giving up Russian oil.
