Regardless of what we think, if you asked the financial media / analysts what the most trusted source for Tesla leaks is the number one answer you'd get would be Electrek. Fred's reporting matters and Elon knows it. In fact he's denied reports made by Electrek multiple times in the past.
I think it is a shame that this has leaked.
I don't blame Fred, once he has the information the temptation to publish is strong.
Good chance the leaking party is a young junior factory employee, unless Tesla confiscates all mobile phones and cameras at the factory this is herd to prevent.. smuggling a cell out for a quick photo might be hard to prevent...
So I don't blame anyone, but it is unfortunate.....
Now tab-less cells are confirmed I give the metal-air hybrid battery some (remote) chance, the reason for that is tab-less cells will require a re-think on thermal runaway protection.... I will not go into the details here, but the metal-air battery is a kind of potential "security blanket" for thermal runway, main battery failure, and range anxiety
There is also lots of areas the Limiting Factor covered that are possible inclusions, so even with the leak there is lots we don't know.
What we still don't know would be very hard for a junior staff member to leak... So the pool of possible leakers for additional information is very small.
