BAB "Battery Autonomy Booster"

Silicon nanopowder for energy storage enhancement

April 2019

Gallery BAB "Battery Autonomy Booster" 1


The BAB (Battery Autonomy Booster) is a set of carbon-coated silicon nanopowders that increase the energy storage capacity of Li-ion battery anodes.

The nanoparticles produced by Nanomakers are prepared on an industrial scale by a technology unique in the world at this scale: laser pyrolysis. There are significant advantages to using BAB. The particle size distribution is the narrowest and the best controlled for particles smaller than 150 nm (nanometers). A large scale production is completely feasible with BAB, and the chemical purity is very high. Another important advantage is that the carbon coating is achieved at the same time as the synthesis of nanoparticles. Given the increase in energy storage capacity, the autonomy of the battery between two charges is increased. Additionally, silicon is preserved from oxidation thanks to the carbon coating.
