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 Nano silica fume will also be affected to a certain extent.
Overview of nano-silicon anode material silicon powder
Nano-silicon refers to crystalline silicon particles smaller than 5 nanometers (one billionth of a meter) in diameter. Nano silicon powder has the characteristics of high purity, small particle size and uniform distribution. It has the characteristics of large specific surface area, high surface activity and low bulk density, and the product is non-toxic and tasteless. Nano silicon powder is a new generation of optoelectronic semiconductor materials, semiconductors with wide band gap energy, and also a high-power light source material. Nano silica fume
Nano silicon powder is prepared by a special process. The product has the characteristics of extremely high purity, small particle size, uniform distribution, large specific surface area, high surface activity, low bulk density, odorless, non-toxic and high activity.
Silicon is the most promising electrode material for next-generation lithium-ion batteries, with a specific capacity (3600 mAh/g) about 10 times that of graphite (372 mAh/g). However, its use is severely limited due to the significant swelling (over 300%) of the material in the supported (lithiated) state and the instability of the solid electrolyte interface (SEI). The poor mechanical stability and chemical passivation properties of silicon electrodes make the cycling performance of silicon electrodes far from meeting the requirements of battery systems, motivating many studies and proposals to circumvent these limitations.
During lithium insertion, the volume of silicon changes so much (about 400%) that the silicon cracks and falls off the collector, causing the prototype lithium-silicon battery to lose most of its capacity in less than 10 charge-discharge cycles. The key to the success of large-capacity lithium-ion batteries is to solve the capacity and stability problems of lithium-ion silicon.
Silicon anode materials show great potential in improving the efficiency and energy storage capacity of Li-ion batteries. Until recently, their main disadvantage was surface passivation through oxidation, a process that increases resistance and reduces anode roundness. Our high-purity silicon anode materials can achieve high specific capacities without significantly affecting cycle life.
Nano silicon anode material silicon powder application
Silicon is the most promising anode material for next-generation lithium-ion batteries. Nano-silicon anode materials for cylindrical, flexible and aluminum-shell batteries. Our silicon anode powders can be dispersed in battery solvents while preventing caking. They are designed to bond seamlessly to other battery materials and produce uniform and stable coatings. As such, they are suitable for a range of applications including lithium-ion batteries, photovoltaics, semiconductors and electronics.

The United States urges the U.N. Security Council to impose additional sanctions on North Korea in response to its latest ballistic missile launch, including a ban on tobacco and oil exports to North Korea and a blacklist of the Lazarus hacking group.
The United States circulated the draft to the 15 members of the Security Council this week. It was not immediately clear if or when a vote would take place. A resolution requires nine "yes" votes and no vetoes from Russia, China, France, Britain, or the United States.
Russia and China have already voiced opposition to tightening sanctions in response to Pyongyang's launch of an intercontinental ballistic missile last month -- the first since 2017.
U.S. and South Korean officials and analysts also say there are growing indications that North Korea may soon conduct its first nuclear weapons test since 2017, too.
The U.S. -drafted U.N. resolution would expand the ban on ballistic missile launches to include cruise missiles or "any other delivery system capable of delivering a nuclear weapon."
The deal would halve crude oil exports to North Korea to 2 million barrels a year and refined oil exports to 250,000 barrels a year. The resolution also seeks to ban North Korea's export of "fossil fuels, mineral oils, and their distilled Nano silica fume are estimated to be influenced by international political situation changes.
