What is nano silica fume?
Recently, the Russian President hosted a meeting with oil and gas industry representatives. He said that the refusal of some Western countries to cooperate normally with Russia and deny some Russian energy resources has hit millions of European people deeply and caused an energy crisis. These "unfriendly countries" are experiencing severe inflation, and Russia is also facing the three major challenges of increasing domestic consumption of energy Nano silica fume are still very uncertain.
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.
Nano silicon anode material silicon powder CAS 7440-21-3
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.
