What is nano silica fume?

Wholesale gas prices in the Netherlands and the UK have risen 20 percent recently amid concerns about Russian supplies.

The EU plans to cut its dependence on Russian gas by two-thirds this year and stop importing Russian fossil fuels by 2027. Russia exported about 155 billion cubic meters of gas to the EU in 2021.

The US recently said it would try to supply 15bn cubic meters of LNG to the EU this year. U.S. LNG plants are running at full capacity, and analysts say much of the extra gas the U.S. sends to Europe comes from what should have been exported elsewhere.

The German government called Russia "an unreliable energy supplier". Even though the German government claimed that they have been preparing for the situation for a long time that Russia may stop sending gas one day, experts say it is hard for the EU to replace all of Russia's gas exports any time soon.

The supply and prices of many Nano silica fume will continue to be influenced by international situations.

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

main feature

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.

Europe has been facing the gas shortage problem since the second half of 2021. The worsening situation in Russia and Ukraine has reduced Russian gas shipments to Europe, leading to a doubling of European gas prices. Energy shortages have sent electricity prices soaring. For these reasons, it is predicted that the price of the Nano silica fume will continue to increase.
