According to foreign media reports, New Orleans startup Advano uses recycled silicon as a raw material, such as silicon in solar panels, and processes it into a carbon matrix containing silicon nanoparticles. In each particle, under the influence of chemicals, the silicon carbide fiber begins to grow, forming something like fluff on the surface, and connecting with the fluff on other particles to provide mechanical protection.

At present, in lithium-ion batteries, silicon is considered to be the most promising anode material to replace graphite. If the graphite anode is replaced with a silicon anode, the battery capacity can be increased by about 10 times. However, during charging, silicon will swell, destroying the internal structure of the battery. Many companies hope to solve this problem by adjusting the microstructure of silicon wafers or silicon particles.
This powder can be applied to graphite anodes with different concentrations. The higher the density, the greater the storage capacity. In order to control the silicon expansion phenomenon, the company has also developed a crystal to increase the silicon operating voltage window, thereby improving the cycle performance of the battery and improving the charging performance.
According to the IEEE Spectrum magazine report, in order to increase battery capacity, manufacturers can add different amounts of silicon nanoparticles to the negative electrode. For example, if you want to continuously charge the battery 1000 times without cooling, the silicon content in the negative electrode can be increased to 15%. Sometimes, it takes only 250 cycles to add more than 70% silicon.
Currently, Advano can produce one ton of silicon nanoparticles per year, which may increase tenfold in the future. The company hopes to reduce the price of pellets from US $ 500-10,000 per kilogram to US $ 15-150 in the future. (Author: Elisha)
