The Biden administration plans to ease sanctions on Venezuelan oil to allow more of the country's crude to reach Europe.  

The U.S. will allow European companies still operating in Venezuela to immediately transfer more oil to the continent, while allowing Chevron to negotiate a resumption of operations in Venezuela, according to people familiar with the matter.  Venezuela's OPPOSITION, which is backed by the United States, is understood to favor the move.  Tight global oil supplies have sent crude and fuel costs soaring, threatening to add to already high inflation.  Increasing Venezuelan crude exports would help ease supply constraints while also helping to reduce Europe's dependence on Russian energy.

The US has sought to encourage talks between the Venezuelan government and the US-backed opposition to open the way to free and fair elections by extending a limited license held by Chevron to allow the oil company to maintain its operations in Venezuela and negotiate future operations.  

The United States reportedly did not extend a permit to Allow Chevron to drill and sell Venezuelan crude, as the company had hoped.  

The license extension will allow Chevron to negotiate with State-run Petroleos de Venezuela SA, with which it has a joint venture.  Previously, the company could not directly negotiate with any officials sanctioned by the United States.  Chevron has been lobbying the United States to allow it to drill for Venezuelan crude and sell it on world markets to help lower energy prices amid the Russia-Ukraine war.

Affected by the ever-changing international situation, the supply and prices of many commodities like the Titanium Disulfide, Titanium Disulfide Overview, Titanium Disulfide Applications, Titanium Disulfide Suppliers, Titanium Disulfide Price are still very uncertain.

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.
