Its not pure silicon. Its a silicon composite particle. The difference between other commercial silicons (like that in every Tesla) is that you not combining silicon (silicon oxide usually) with graphite. The problem is we don't actually know what is in Sila Nanoparticles, but I am pretty sure its not 100% silicon. Removing graphite is the claim to fame here.

Correct. Tesla, and many others, are working on similar concepts where it is silicon nano particles encapsulated with some other material. I'm betting that's what SilaNano is doing. This, in theory, allows the silicon to expand without cracking, which has been the major issue with silicon anodes so far. Here is an image from Tesla's "battery day" that gives a visual idea about the issue/potential solution: https://cdn.shopify.com/s/files/1/0173/8204/7844/articles/SSS_1024x1024.jpg?v=1601325098 https://cdn.shopify.com/s/files/1/0173/8204/7844/articles/SS...

  No, Tesla is actually not using Composite Nano particles. They are using micro particles that are coated with a polymer and then mixed with graphite and a binder. This is quite different. In that version you contain the silicon expansion not by having complex composite particle but rather by having the polymer contain the cracking.

They have not released a picture, but Talga resources has a silicon composite product and they have a picture: See this: https://youtu.be/WeTAC6Xe4Uw?t=1557 https://youtu.be/WeTAC6Xe4Uw?t=1557 In general Limiting Factor on yt has by far the best videos on this: #5 The Science Behind Tesla Silicon - https://www.youtube.com/watch?v=YTW_Q63bEEY https://www.youtube.com/watch?v=YTW_Q63bEEY #7 Tesla Silicon is Disrupting Silicon Disruption - https://www.youtube.com/watch?v=AL6xp4fLdFw https://www.youtube.com/watch?v=AL6xp4fLdFw He also has the interview with Talga about their Si product: Mark Thompson - Talga https://youtu.be/WeTAC6Xe4Uw?t=1506 https://youtu.be/WeTAC6Xe4Uw?t=1506 And also with interview with Sinanode: Sinanode: Low Cost Silicon Nanowire Coated Graphite for OEMs - https://www.youtube.com/watch?v=ySCFZIWMYQA https://www.youtube.com/watch?v=ySCFZIWMYQA There is also : Professor Shirley Meng: The Future of the Anode (C, Si, Li) - https://www.youtube.com/watch?v=0ktsgwzUh3A https://www.youtube.com/watch?v=0ktsgwzUh3A
