First look at Tesla’s new battery cell produced in-house with Roadrunner

FYI: The story was just about Elon’s tweet so nothing new.

Anyone else besides me think the new battery pack kinda looks like a beer can?

When I saw it in hand I thought, about the size of a Red Bull.

That is the mindblowing news Elon has been promising...the new batteries will be powered by Redbull! The only downside is Teslas handling will now feel a little jittery.

It's a more environmentally friendly electrolyte......

I'm eagerly anticipating what this might mean. If it is something like 20% to 40% increase in energy density, then range just increased significantly while reducing weight. I can't wait until next Tuesday.

I wonder if anybody has tried to separate the contribution of energy density of the chemistry vs energy density at the pack level due to fewer voids. I guess this is the difference in Watt/KG Watt/liter. The recent Sandy Maduro break down really brought the reduction in voids to my attention.

There's a slide in the battery day presentation that does this:

The range increase is basically your volume question, tho its answer is mixed between arrangement and new materials in the car. The slide with the power/range answers the arrangement question more directly.

It says it's a small increase in volume from form factor alone. But has you can see from the other slide, the entire pack sees a boost, like Munro said.
