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. See this image: https://youtu.be/YTW_Q63bEEY?t=929 https://youtu.be/YTW_Q63bEEY?t=929 Sila on the other hand is creating a more complex silicon particle that is partly empty and can expand without 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
