Yes some are working on 100% silicon anode (Sila, Amprius) but even with carbon coating and nano size there are many challenges and resolving those challenges is costly and probably that those would not be economical for mass production, and especially a challenge to include in cylindrical batteries like Tesla uses. It's easier to manage the swelling in a pouch cell instead and that is what Sila and Amprius are making with 100% Si anodes.
Yes, even the new byproduct has a better performance than graphite in a lab setting but that's not to say that the challenges from Silicon's swelling (cracking of the particle, cracking of the SEI layer, etc) don't appear when going to higher content.
So my take is that, while yes Tesla could be interested in our product, they wouldn't go to 100% Si anodes, but also that Sila and Amprius could easily be the battery manufacturers requesting our product samples for their 100% Si anodes. There could also be Talga and Novonix who are both working on a composite NanoSi-Graphite particle as potential clients.
The important thing remember is we'll create the cheapest 2N-4N mettalurgical grade Si, and the cheapest NanoSi with an optional carbon coating, so any Si anodes would be cheaper with HPQ Silicon.

Of course this may be solved by using a different electrolyte or with further advancements but so far a 30% silicon anode looks to be the most promising.
hmmm yes....the limiting factor...and exactly what size of silicon was he referrring to? Was it nano silicon? How about carbon coated nano silicon? Did he have all the data on that to determine 30% was the the maximum and most efficient? Oh what about a biproduct of silicon that hpq thought was important enough to put a patent on? Does he have the electical characteristics of that by any chance? One thing i have always lived by is that as much as one person is an expert in there is always someone somewhere that knows more..
