Something's stirring over at Tesla. The company's highly anticipated Battery Day is just on the horizon, and ahead of the event, CEO Elon Musk shared some insight into energy density via Twitter.
Replying to a Twitter thread surrounding the possibility of an electric airplane, Musk said batteries with 400 watt hours per kilogram are highly likely in the next three to four years. And not just one-off units, either, but mass produced batteries with long lifecycles, too.
This type of energy density could provide 50% more energy density compared to today's batteries, noting today's batteries used in the Tesla Model 3 feature an energy density of about 260 Wh/kg. The more energy packed into a battery, the longer the driving range for a vehicle.
In conjunction with Musk's comments, Tesla itself released a teaser showing a peculiar pattern with numerous dots. Reuters reported the pattern could hint at silicon nanowire anode, which if realized, could help Tesla achieve more energy dense batteries with longer usable lives. Tesla did not immediately respond to a request for comment.
This year's been rife with speculation surrounding Tesla battery news. From Panasonic's pledge to boost energy density in the years to come, to China's CATL's work with Tesla on a "million-mile" battery, there's been no short supply of energy-related news. Tesla also applied to become a utility provider in the UK earlier this year, just as we learned more about the company's Autobidder system to manage their energy production and sell electricity back to the grid.
We've got less than a month to go before Battery Day kicks off on Sept. 22, and we'll surely hear more before then. Musk likes to share on Twitter. A lot.
What about the environmental impact from manufacture and disposal I wonder
Potentially good news.
Batteries have for SOOO long have had a poor “Moores’s Law” trajectory.
Batteries vs. Capacitors....
“What about the environmental impact from manufacture and disposal I wonder”
I really doubt you care.
Unless the batteries are interchangeable between vehicle brands much like gasoline goes in any car I don’t think electric is the way...just my 2 cent.
Disposal won't be a problem......................
There was an article a couple of days ago about batteries that are self charging made from processed nuclear waste.
The Electrons are the same [as gas/Diesel are], but the battery gas tank geometry and chemistry can be very different. A “battery” is not just a vast, empty, enclosed space, -unfortunately.
Maybe he should consider where all of this electricity is coming from, and use some of the big brain he hires to make small safe nuclear reactors. I know he has married women and super models to chase but I would think he could fit it in between spacex launches, tesla announcements and audultery.
A two-fer!................
Rather than post a new topic -- it was Battery Day at last, virtual shareholder meeting, original is over three hours I think, this boils it down. Try a search on "Battery Day in 14 minutes" for many more such.

The theme was greatly increasing productivity and greatly reducing costs so that Tesla can take over the world.

Don't show the meth cookers this pic, they'll flip out!
..but anyway...

I was surprised at the estimate of how much the production line will shrink in terms of plant footprint, that could (not necessarily would) mean battery plants going in rubblefields/tax holiday sites up here in the rust belt.
The only way Tesla can live up to the lofty market cap now assigned, is if the US Govt forces the cars upon us.
Otherwise, as a stand alone operation, there isn’t enough resources and sales opportunity or available electricity to create vehicle numbers high enough to justify the stock price.
