Tesla battery day 9/22

I'm looking forward to livestreaming the Tesla Battery Day announcements.  If Elon is saying  it "blows his mind," I'm sure we're looking at some major tech advances.

I don't think that will include a new rv battery chemistry, 😆, but there's always hope for a new, scaleable, more affordable alternative.

Interesting article (fairly technical) .... https://marker.medium.com/why-teslas-battery-day-will-actually-live-up-to-the-hype-f10b4c74dc9b

I agree, John. Read that one, too. It is technical,  but not so deep that most folks can't "get it." I actually thought it was one of the better speculative reports out there.

My hope is for better, longer lasting, cheaper batteries. 

I will say the two years in, I'm really, really happy with our Tesla powerwall installation.  BUT, hopefully,  it will be "old school" soon. 

A week away is not a long time to wait.   Lots of speculation.

So, the news itself was exciting, but the outdoor event (with the shareholder audience sitting in a couple hundred Tesla 3's, tooting horns in place of applauding) had little of the glitz and fun of a Tesla vehicle launch. (I had a hard time staying awake through parts of the two hour livestream, actually.)

The big news items:

A new, bigger tabless battery cell, the 4680, to be built in-house, by Tesla, with streamlined manufacturing to reduce the time and cost. The new cell will increase energy by 5x, power by 6x, and add 16% to the range. Tesla will continue to buy from others for many of their cars, so my guess is the new battery technology may go into the cybertruck.

Phase out the use of cobalt, and diversify chemistries of cathodes. Announced plans to build their own cathode factory in North America.

Cut the cost of battery packs by 50 per cent, eventually. All of the above will allow building an affordable 25k Tesla.
