The five times more energy dense and 6 times the power refers to the design explained on Tesla's Battery day. Seriously, they made a 2 hours presentation about it. Total nerd porn : https://www.youtube.com/watch?v=l6T9xIeZTds https://www.youtube.com/watch?v=l6T9xIeZTds
This really applies to the cells, not the battery itself, I think they just misunderstood. This is in comparison to the current design. They did that mostly by... making the cells bigger! I think the battery itself is 35% smaller because this removes the need for using tabs and the cell volume/surface area is greater.
Also note that "six times the power" doesn't mean six times the range. Power is energy per unit of time so it really only tells you how fast you can use the energy in your battery (and I'm assuming how fast you can charge.)
- Someone 5y agoYeah, “six times the power” was a lapse of me. Intended to copy-paste the “five times the energy” part. The math still doesn’t hold up, making this article as good as content free for me. History so far tells that we can’t trust their projections on price and delivery date, not to mention full self driving. So, the content for me is “Tesla is working on a hatchback”.
- maximus-decimus 5y agoI think what you're missing is the big improvement comes from removing the tabs. This allows them to remove a ton of dead weight basically. But yeah the article is terrible. It's like they decided 9 months late to make an article about Battery Day.
