SCALABLE MANUFACTURING PROCESS INTEGRATES EASILY WITH TRADITIONAL ANODE PRODUCTION

SiNANOde® production starts with one of the best commercially available types of graphite.

A deposition process adds catalyst nanoparticles onto each graphite particle to later initiate nanowire growth directly onto the graphite in commercial CVD furnaces .

The silicon nanowires remain attached to the graphite throughout slurry mixing, anode coating and calendering, and throughout the full battery life of cell charge-discharge cycles. This ensures that electrons can always flow between the anode current collector and the silicon nanowires during lithiation and delitihation, thru the graphite particles.

The size of the catalyst nanoparticles and their surface density on graphite particles are determined by the catalyst synthesis and deposition process. The average length of the nanowires is determined by the CVD process. Together, these parameters determine the final silicon content per gram of graphite. .

Thanks to a proprietary reactor design, each CVD furnace converts 99% of the Silane gas into silicon nanowires attached to the graphite particles.

The resulting SiNANOde® powder can then easily replace the standard graphite (or be mixed with the graphite) to make a slurry applied onto electrode foil using traditional roll-to-roll production equipment.
