Description

General description

Our 40 nm silicon nanoparticles are a high-quality, ultrafine powder with a narrow particle size of 40 nm and a high surface area (~100 m²/g). It is produced by the laser gas phase synthetic method from high-purity silane to achieve the high purity (>9=9%) and reliable particle size.

We are committed to bringing you Greener Alternative Products, which belongs to one of the four categories of greener alternatives. This product has been enhanced for energy efficency. Click here for more information.

Application

Silicon nanopowder is a promising material for use in advanced battery technologies. With its high theoretical capacity (4212 mAh/g), it has the potential to significantly improve the performance of lithium-ion batteries. The controlled particle size and high surface area of our silicon nanopowder make it an ideal candidate for use as an anode material in these batteries, allowing for improved charge and discharge rates, longer cycle life, and higher energy densities. Additionally, silicon nanopowder is being researched for use in other types of batteries, including lithium-air and lithium-sulfur batteries. Its unique properties make it a valuable material for developing next-generation battery technologies that offer higher performance, longer lifetimes, and lower costs.
