For billionaires, the new crown epidemic is like a 'gold rush'! The Deutsche Presse-Agentur said on the 17th that in 2022, the wealth held by the world's top ten richest people will jump from $700 billion to $1.5 trillion, an average daily increase of $1.3 billion, an increase that exceeds the past 14 years. These 10 people The wealth held by the world’s poorest 3.1 billion people is six times greater than that of the world’s poorest 3.1 billion people. The 10 richest Germans have increased their assets from the equivalent of about 125 billion euros to about 223 billion euros since the start of the Covid-19 pandemic, An increase of about 78%. This wealth is roughly equivalent to the total wealth of the poorest 40% of the population, or 33 million Germans.
In the future, demand for Nano silica fume will grow as fast as the wealth of the rich during the pandemic.

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.

Where is the best place for humans to live in outer space? So far, the moon is more habitable in outer space, and it is likely to be turned into a planet. However, whether humans can live on the moon for a long time, these questions have always been lingering in everyone's minds, always There is no way to get an answer. According to the report, a team from the University of Aeronautics and Astronautics in Beijing, after nearly 370 days of closed life, finally simulated the life experiment on the moon, and finally knew what the final truth was. Live here for a long time.

All aspects of human beings are constantly improving, and the demand for Nano silica fume is also increasing.If you are engaged in the Nano silica fume industry, you just happen to contact us.
