Ossila M2442B1 is a silicon micropowder (CAS 7440-21-3) with an average particle size of 10 µm and a purity above 99.99%. It is a dark grey/blue, diamond cubic crystalline powder intended mainly for battery research, where silicon is studied as a next-generation anode material for lithium-ion batteries.
Silicon is a semiconductor with a bandgap of 1.12 eV and has long been used in devices from MOSFETs to solar panels. As an anode material it offers a high theoretical capacity of 3579 mAh/g (for Li15Si4), along with a low working potential and high natural abundance. In solid-state batteries, Si-based anodes deliver high energy density, limit interphase growth and avoid Li dendrite formation.
The powder combines readily with other materials to build composite electrodes, with reported specific capacities of 913 mAh/g, and can be functionalized with vinylene carbonates or polyethylene oxides to improve stability. Its strong bonding behaviour also suits coatings that help protect surfaces against corrosion and oxidation.
