RE:RE:Silicon pulverization problem, 45% dead weightHe's got over 100k views on each of his latest videos, and has promised a series of new videos post-battery day that still hasn't begun. Can't wait to see his take on silicon anodes from metalurgical grade Si as stated by Elon, he might talk about HPQ, one can hope...

He goes through the SilLion patent on the cell design and adds in the complementary battery technology solutions Tesla has aquired to form a cell like we pretty much seen on Battery Day.
Reviewing this, I noticed tesla also showed on battery day the manufacturing of the silicon anode slurry/ film that would be bonded to the copper substrate. This was that black film they showed apart of cell manufacturing design.
Tesla literally have been preparing SilLion anode commercial assembly lines with high cost silicon materials, in expectation for us to enter with our low cost feedstock solution.
Pitpitcolisse wrote: At around 15 min in the video, this battery expert explains that at 80% sillicon content, the np ratio is 1.8 because the silicone pulverizes itself at first charge and becomes 45% dead weight. We know that to overcome this, the key is HPQ's nanopowders at an accessible price. By fixing this issue, the anode could have an np of 1.2 and reach the levels Tesla claims to be aiming in 2 years... https://www.youtube.com/watch?v=cPCnWiwdtbg&ab_channel=TheLimitingFactor
