Porous silicon is a new generation of photoelectric, pharmaceutical catalyst carrier and new energy material, applied to the negative electrode of new energy lithium ion battery, can increase the capacity by more than 3 times, with 20% directional volume expansion; In the carrier application can improve the antibacterial and conductivity.

Features Porous micron silicon is produced by chemical alloy method, with high purity, stable structure and pressure resistance, and stable "ant nest" structure. The micro size is nano structure,the particles are micro structure, which can solve the problems of bulk density, dispersion and expansion of traditional nano-sized silica powder.
