While Sodium-Ion sounds legitimately promising, we’ve all read so many articles about “revolutionary new battery tech” over the years that the default response is “cool, let me know when mass production starts.”
Can buy them in relatively small quantities now online.
("to the best of my knowledge, that is now, immediately.")
Yup. BYD's 30GWh/year means 1kwh/second!
I can't resist cancelling the units even though it doesn't actually make sense because it's a capacity not a volume, as it were, but that's a 3.6kw factory!
The article literally starts off with a mass produced $800 Sodium Ion battery that you can buy right now.
Because it's an ad..you all know that,right?
You don't generally advertise things that you don't mass produce, though.
Did..did you want them to keep it a secret?
It being an ad doesn’t change anything in an of itself. They’re correct in saying that there is a mass-produced, consumer grade product available. Unless that is a lie, or said product is complete trash, this solves the “call me it’s mass-produced” problem the original commentor has.
I only pay attention if Dr. Goodenough's name is somewhere in the ecosystem.
Did you read the article? This isn't about a research paper that talks about theoretical lab experiments. Sodium batteries are in real world application right now. Mainly in China and South America.
You can buy sodium batteries from AliExpress. It's been available for a while. I was thinking about ordering a few but I ended up spending my hobby budget elsewhere. There's no economies of scale yet for sodium battery tech. You can get the battery but there is zero electronics available for it. Mainly you'd have to design your own charger and battery management modules. That's out of my pay grade. I've been waiting for Chinese engineers to mass produce such things.
i hope isdt releases a firmware update for the q6 nano for that if RC sodium ion packs become available.
although afaik energy density per volume and weight isn't quite there yet
You can buy a lot of bullshit from AliExpress.
they're actively manufactured for consumers, and cheap and available enough to be relatively competitive with lithium ion on there
The sub is about technology, not industry. Also, look at the advances in battery technology in the last 30 years. There have only been 3 notable technology advances in the last 40 years from a consumer perspective, but there have been significant advances within each of those major technology changes, resulting in Wh/kg increasing by 6 to 10 times and $/Wh dropping about 99%.
If you want to hear about things that could happen or are about to start happening in industry, this is the right community. If you want to know what you can buy tomorrow, try Amazon.
Feels weird to gatekeep that - the des says 'news or articles' so an article about some ancient tech isn't for this community?
I understand it as anything tech related, that explains/talks about technology, manufacturing tech included.
The 'not industry' part as in macroeconomics & geopolitical stuff - I agree on that.
The point is not about this particular article, but the general attitude of that comment, which boils down to "Why is there an article about a technological breakthrough that may never pan out in my community about technology?" I feel like these guys would have complained about Newton's quaint ideas for a new way to use mathematics. The fact this particular article is about technology that is demonstrably taking off while they complain about articles on battery tech not being implemented is pretty next level.
Oh, I see.
I was just commenting on 'this community isn't about industry' bcs I didn't quite understand that (but my comment was a bit unclear, should have added the quote I was referring to).
All good. I just keep seeing this all the time about batteries, simply because most of the technological advances are slow, cumulative, aggregate, and largely invisible to consumers. Then people complain about how none of these advances ever make it to market while ignoring, for example, how many pounds old, barely capable cell phones were compared to the functionality of smartphones these days that can run for a full day on a battery a fraction of the size we had for those old behemoths, all apparently without any of those breakthroughs making it to market. I mean, look at the first cell phone in this article. I suspect some advancements occurred in batteries between then and now.
Oh, I'm fully aware how battery tech advanced and/or awkwardly staggered in some areas.
Phones are a great example, the rise of capacities through diffident technologies were fast & very close for people to experience first hand.
I just wish we would have started this push a century ago.
Absolutely. If we had done so with batteries and solar, imagine where we could have been. Both technologies languished for far longer than they had to.
And yet, a Tesla model S costs $10,000 more than 2012.
look at EV prices in china for a more accurate depiction of the battery progress that is being made
apparently the government EV subsidy for outright purchases ended in 2022, but they're good enough at the manufacturing now that EVs are still exceptionally cheap. 70-80% of world lithium-ion production also takes place in China, so it makes sense.
There's a lot of reasons that I don't like the Chinese government, but they have been doing a whole lot better than the rest of the world with investment into the future of technology from what I've seen. The number of top-rated CS and EE schools in China is doing a whole lot on its own.
I'll take out of context quotes for $100, Alex.
Those changes are over 40 years, only 13 years of which apply to your reference, and include only one component of a luxury vehicle. Also, the current base price for a Tesla Model S that it showed me was $150k. If we apply inflation to $140k since 2012 ($150k minus the $10k you said), we get a value of $197k. So, $47k cheaper in 2025 dollars.
I suppose you blame battery prices for why McDonalds costs more, too?
Tesla, the company run by a nazi capitalist and which has a value so inflated it’s amazing it hasn’t imploded under its own weight, raises it’s prices and you’re blaming batteries? You do know that every saving a corporation makes goes towards profits and that they never lower their prices as long as people are buying(and even then, they refuse to most of the time)?
There’s correlation not equalling causation and then there’s whatever the hell this is. Like one of the final bosses of that logical fallacy.
Yeah, I want to buy a car w/ reduced range at substantially lower prices, but I can't do that right now. Give me a sub-$20k option to get to work and back and then I'll get excited about the tech.
Second-hand Nissan Leaf?
Right, used cars are feasible, I'm talking about new cars. A sub-$20k new commuter should be possible w/ sodium ion batteries.
Buying new cars is stupid. You wasted several thousand just by driving it out of the dealership. Let someone else do that and buy it a year later with low milage and ten grand off.
And the Nissan leaf is an absolute joy to drive.
I buy used cars exclusively. A used EV that retails under $20k new will be very affordable used.
My point isn't that used cars don't exist under $20k, my point is that sodium ion batteries are supposed to be way cheaper than lithium ion batteries, and they're more than sufficient for a commuter. I want those available where I live.
Sorry for the misunderstanding.
In fact, I very much agree.
