Tungsten Disulfide WS2 as Battery Material

In terms of international pricing benchmarks, according to the CP data released by Saudi Aramco, the propane contract price (CP) in March was $895 / ton, up $120 / ton from the previous month, up 15.48% from the previous month and up 43.20% from the same period last year. Butane contract price (CP) in March was 920 US dollars/ton, up 145 US dollars/ton compared with last month, up 18.71% month-on-month, up 54.62% compared with the same period last year; In March, CP in Saudi Arabia rose sharply, giving a strong boost to the international and domestic LPG market. Benchmark LPG prices are higher than a year ago as the economy continues to recover and demand for crude oil continues to repair. According to this trend, the market price of graphene powder will also be affected to a certain extent.

The advent of sodium batteries is expected to alleviate the current constraints of lithium resource shortage on the rapid development of the new energy industry, and will further stimulate the application of transition metal disulfide such as tungsten disulfide WS2 in the field of power energy storage. 
 
Lithium-ion batteries are a key raw material for developing energy devices and realizing the vision of "carbon neutral". However, at present, the capital investment in the raw material end is difficult to cover the rapidly growing energy demand, and there is an obvious structural imbalance in the investment in the lithium electric industry chain, which leads to the rising cost of lithium raw materials. 
 
As a result, sodium batteries began to enter the field of vision. Sodium is abundant in nature, and as an energy material, it also has a large capacity and high-rate performance, which can effectively make up for the shortcomings of lithium-ion batteries in the current energy storage field. Although the price of sodium battery will be higher than lithium battery due to the small scale of the supply chain at present, with the maturity of technology, the cost-effective sodium battery will be an effective supplement to lithium battery, and it is even expected to serve the development of new energy field together with a lithium battery. 



Tungsten disulfide, as a potential battery material, is also expected to benefit from more market replenishment.
Tungsten disulfide is a layered material with remarkable surface effect, electron fluidity, thermochemical stability, and high density of electron states. It has been widely used in lithium and sodium storage. For example, nanocomposites used as conductive additives or graphene composite as anode material of batteries can show higher specific capacity and discharge efficiency, making up for the deficiency of single component WS2 or C as anode material. 
 
Graphene is a new anode material most studied by energy storage researchers in recent years. It has many advantages, such as excellent electrical and thermal conductivity, a large specific surface area, and so on. However, as an energy storage material, it still compensates for its own defects, such as the material is prone to structural collapse under a long cycle, which will lead to a serious decline in battery capacity. Therefore, graphene and WS2 nanomaterials with high thermochemical stability can effectively compensate for the shortcomings of graphene. 
In general, tungsten disulfide is an ideal choice for battery materials.

New Delhi: India is seeking to increase its purchases of crude oil from Brazil, the country's oil minister said recently after meeting his Brazilian counterpart.  

India is the world's third-largest importer and consumer of crude oil. Brazil currently supplies only a fraction of India's crude oil imports.  

India's state-owned companies Bharat Petroleum Corp and Oil and Natural Gas Corp have invested in oil and gas exploration in Brazil.  

India, which imports about 84% of its crude oil needs, is reducing its import bill by increasing biofuel use, among other things.  

India's state-owned fuel retailers are increasing ethanol storage capacity by 51 percent and the country plans to double the biofuel blend in petrol to 20 percent by 2025.  

India and Brazil are currently cooperating on biofuels and ethanol.

The prices of many commodities like the graphene powder are expected to increase in the future.
