#5 The Science Behind Tesla Silicon // Cracking the Silicon Code

How did Tesla crack the Silicon Code? Today we'll discuss the science behind Tesla silicon. It may take multiple technologies to make Tesla Silicon and today we'll discuss the four that I think are necessary to get high cycle life from a high loaded silicon anode. This is part five of the Lithium Mine to Battery Line series.

Thanks Jordan, this is one I was really waiting for. Thanks for making the picture much clearer re the "Silicon Anode" which now I understand is much more than Silicon :). This might be worth looking into: "HPQ Silicon announced that its partner, Apollon Solar of France, has delivered the first batch of carbon coated nano silicon powders to Professor Lionel Roué at the Institut National de la Recherche Scientifique (INRS) for evaluation." HPQ is a Canadian company.

Your videos are always a feast of information. Battery development is like examining all the possible moves in the middle of a chess game in which avenues that initially look promising are often brought up short by show stopping issues later on. It is evident that the problems are complicated and no easy solutions immediately present themselves. So thank you for walking through these issues in an intelligent, logical and thought provoking presentation. As a compendium of the current state of battery development your videos are without parallel.

Good piece, Thanks! Comments:1. Polymer coating TSLA is working on may or may not be only one component/composition. Polyrotaxane is not as electronically conductive.

1, As particles, less than 150nm will cause a significant increase of SEI impact Tesla using Miron-level Si particles; 2, Tesla using elastic binders (Polyrotaxanes, SiLion) and polymer coating (spandex) to avoid SEI crack and make the structure reversible during battery processes (expand and shrink); 3, Tesla add graphite into Silicon to increase conductivity; In that silicon graphite (low cost and easy produce from talga) 4, New electrolyte:tetrahydrofuran and 2 methyl-tetrahydrofuran

[@raddaks2039]

I think you hit the nail on the head when you said that just the tabless design alone was game-changing by itself. I see battery day as an announcement of everything they are working on and a series of things that they'll be rolling out in the coming years to continue decreasing battery cost. Tabless is obviously a lot further along than high-silicon at the current moment. Thanks for the overview! It's really cool tech, and your first-principles, cost-based focus on it is super practical and has a lot higher chance of being correct than the silicon-nanowire-esque moonshots. Also, if this is the executive summary, I can't wait for the deep dive. XD

[@thelimitingfactor]

As a side issue could you possibly discuss 'power on demand' devices such as the E-Cat, and brilliant light powers sun cell system.

[@incognitotorpedo42]

BLP has done hundred hour runs of a 250 kW Sun Cell. They have a KZbin channel with videos, occasionally narrated, usually not. kzbin.info Here is a good video that lays the technology out at the "executive summary" level: kzbin.info/www/bejne/hHiXaWt-mLh8sNU Their technology is based on new physics, and will cause a lot of heads to explode. It's hard to argue with the heat they're generating, though.

[@aljawisa]

@@incognitotorpedo42 I knew he wouldn't address my comment, but I have to put these brainiacs to the test. The stuff I referenced is undeniable stuff. Even internal combustion engines are not played out yet..aka Walter Jenkins, David Yurth. Rex Research, and the Thomas Bearden website are full of things that would make these peoples heads explode. Looking closely at Elon Musk, I believe 'the powers that shouldn't be' have allowed Musk to do what he has done. Without the vaccines I'm sure my IQ would have much higher, so I don't need any cyber whatever, to enhance my brain. (I just need to survive into God's Kingdom; a whole different topic) But those same powers do everything in their power to inhibit human intelligence. Eliminating those vaccines would cause an increase in the rate of human intelligence, especially among the newly born. Not to mention what Bearden talks about in re-engineering the ways in which we transmit information or electricity, ultimately eliminating or greatly reducing electromagnetic pollution. Besides that even Bearden talks about basically doing a 'Jesus Christs,' by triggering and controlling the cells in the body to basically regrow missing parts like a lizards tail. If you didn't have it in the first place as an embryo, what caused it to grow and then stop. So there's ultimately no need for artificial limbs controlled by neuralink. Bet they regrown limbs have done this in an area 51 lab, with all those other Slim Shady clones. I did find some research on that particular topic in the past, but it might be hard to find it now. humanlimbregeneration.com/how-can-stem-cells-regrow-limbs/ www.ibtimes.co.uk/us-scientists-plan-grow-new-limbs-amputees-stem-cells-1515611 In addition most of these science channels on youtube are in the stone ages. To me these people are like Dr. McCoy, in Star Trek 4, complaining about drilling holes in Chekov's head. I found a few channels on youtube talking about how to remineralize your enamel and dentin. I tried the formula, from one of the channels, and after about 6 months, the two carries in both of my teeth had mostly remeneralized. The tooth that was more natural with smaller old fillings regrew more than the tooth that had more fillings. Thank god the tooth with more fillings had a small carry. I'll check again in 6 more months to see if they completely recover. My point is that if just listen to 'the powers that shouldn't be,' you'll never get the "best" answer you're looking for, it's usually a complicated compromise, where you're never truly free. You're just an ATM to them. One day, as I've heard, Elon will stop selling Teslas. Basically those powers never want you to be free. Theirs a lot of perspectives on that 'I won't sell Teslas anymore' I don't feel like typing about. But It help me to see why Elon was allowed to produce the things he wants. Only elites will make it to mars. Cyber link will make it more easy for the government to control your brain. (I personally think there are 2 levels of mind control, but the higher level form of mind vs mental state mind control needs much more specific attention to the individual, such as drugging them. The mental state mind control is very broad.{5G} neuralink will be much more personal and allow the hacking vote stealing government to directly control what you see. Plus more people will buy into cyberlink according to the hype I'm hearing. But I suppose you could use both 5G and neuralink together to turn many into Al Rokers, or Britney Spears, or Mark Suckerberg) I know Elon is not the man you (me) think he is. And from time to time he'll slip up, and reveal he absolutely does know about non-Newtonian physics (if he gets to Mars or the Moon its a grave yard of higher dimensional ether physics devices/artifacts that basically flip the bird to Newton, that he'll have access to study{maybe like data's head}), kzbin.info/www/bejne/f2KmaHePgMSKZqM and deeper conspiracies. He may be playing some kind of game where he might be using the NWO's plans like Judo, where he does what they want but at some point the things he set in place may be used against them. It's hard to determine what the guys plans are. Don't know weather he's a good guy or a bad guy. But I can see how bad people can use the things he's trying to pursue to harm or control the public.
