Nothing factually wrong with the article, but it has this sound of "this technology will solve all our problems" to it that I find highly problematic. Seven out of nine planetary boundaries are exceeded, climate change just being one of them. And all of them are exceeded because of our wasteful and growth-oriented way of life.

Because of ~~our wasteful and growth-oriented way of life~~ capitalism.
FTFY.
I don't doubt for a moment that humanity can be extremely wasteful in any economic system. But capitalism sure embraces and enhances our worst tendencies.
Partially. It's more that people don't click unless the headline is sensational.
We can change our technology to be more sustainable or we can regress to a pre-industrial society with 90% of the population dying in the process. Which do you prefer?
That's a false dichotomy. We can also improve our technology while ditching capitalism.
That's reductive. Seeing capitalism as the root cause of all problems is disingenuous. The particular ideology oligarchies are using to justify their rule is incidental.
But... It is the root of a lot of problems and it helps the oligarchs... And it just sucks and makes no sense in general?
Personally when I say I want to ditch capitalism, the first thing I think of, among many, is simply about democratizing the workplace. Cooperatives have proven themselves to be superior than the current private model in a variety of metrics. If we reduce the defining characteristic of capitalism as needing capital to produce more capital, the current issue is that cooperative enterprises struggle to obtain the initial capital necessary to get started. Even though they have much greater success rates, banks have historically refused to give loans to these endeavers. There exists non profits to try and fill this void but its not enough.
No, it's not. Not seeing that it's capitalism is the reductive view. Instead of trying to type down a huge text while I'm tired, I'd like to introduce a 112 year-old text that still seems extremely relevant today:
Moreover, capitalist production, by its very nature, cannot be restricted to such means of production as are produced by capitalist methods. Cheap elements of constant capital are essential to the individual capitalist who strives to increase his rate of profit. In addition, the very condition of continuous improvements in labour productivity as the most important method of increasing the rate of surplus value, is unrestricted utilisation of all substances and facilities afforded by nature and soil. To tolerate any restriction in this respect would be contrary to the very essence of capital, its whole mode of existence. After many centuries of development, the capitalist mode of production still constitutes only a fragment of total world production. Even in the small Continent of Europe, where it now chiefly prevails, it has not yet succeeded in dominating entire branches of production, such as peasant agriculture and the independent handicrafts; the same holds true, further, for large parts of North America and for a number of regions in the other continents. In general, capitalist production has hitherto been confined mainly to the countries in the temperate zone, whilst it made comparatively little progress in the East, for instance, and the South. Thus, if it were dependent exclusively, on elements of production obtainable within such narrow limits, its present level and indeed, its development in general would have been impossible. From the very beginning, the forms and laws of capitalist production aim to comprise the entire globe as a store of productive forces. Capital, impelled to appropriate productive forces for purposes of exploitation, ransacks the whole world, it procures its means of production from all corners of the earth, seizing them, if necessary by force, from all levels of civilisation and from all forms of society. The problem of the material elements of capitalist accumulation, far from being solved by the material form of the surplus value that has been produced, takes on quite a different aspect. It becomes necessary for capital progressively to dispose ever more fully of the whole globe, to acquire an unlimited choice of means of production, with regard to both quality and quantity, so as to find productive employment for the surplus value it has realised. From Rosa Luxemburg: The Accumulation of Capital, Chapter 26 - The Reproduction of Capital and Its Social Setting
This passage is kind of an introduction to Rosa Luxemburg's definition of imperialism. Back then, capitalism was not yet developed in the whole world and she argued that simply because it's a question of survival for companies, these companies will push for the right to exploit the whole world. And now, 112 years later, I'm pretty sure we can agree that happened. And in the past few decades, when they can't expand spacially, now it's all about squeezing every last bit of profit from nature, the workers and the consumers.
The particular ideology oligarchies are using to justify their rule is incidental.
Here, we have a point of agreement. The USSR developed into something that was no better than capitalist states. In my opinion, that's because it's bureaucracy developed into something very similar to the burgeoisie in capitalism, resource hoarders led by self-interest.
But I believe your answer built on another false dichotomy here. The alternative to capitalism I have in mind isn't a one-party state with central planning and communist aesthetics. I'm more of a proponent of decentralized power, dismantling the state and people governing their surroundings cooperatively.
Question: would I have to give up my exploitative companies that fuel my bid to become the first King of Internet? Because that's kind of a dealbreaker for me.
What are you talking about, you filthy usurper? I'm the only legitimate king of the internet!
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.”
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?
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.
You don't generally advertise things that you don't mass produce, though.
Somebody gotta tell Silicon Valley about that.
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.
You can buy sodium batteries from AliExpress.
You can buy a lot of bullshit from AliExpress.
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.
Can buy them in relatively small quantities now online.
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.
HiNa supplied sodium-ion batteries for JAC Motors in 2023. Early batteries had lower gravimetric energy density (145 Wh/kg) and volumetric energy density (330 Wh/liter) than LFP, but sodium-ion batteries have already improved since then. They have outstanding temperature range, yielding 88% retention at -20°C. For reference, the discharge capacity of NMC at 0°C, −10°C and −20°C is only 80%, 53%, and 23% of that at 25°C. The HiNa batteries had a cycle life of 4,500 cycles with 83% retention and a 2C charge rate, but even better sodium-ion batteries are on their way.
...
These developments point the way to much more. The cost of sodium battery materials is much lower than for any lithium battery. There are no resource bottleneck materials like cobalt or lithium to contend with. In addition, aluminum can be used for electrodes, whereas lithium requires copper for one of the electrodes. Carbon or graphite and separator materials will be similar, but in all other respects, sodium has much lower material costs. Compared to LFP, sodium does not require phosphorous, a substance that is almost exclusively sourced from one state in north Africa, nor lithium, a relatively abundant but more expensive substance than sodium. LFP cannot compete on material costs or temperature range, and both BYD and CATL expect to phase it out first in energy storage.
Early batteries had lower gravimetric energy density (145 Wh/kg) and volumetric energy density (330 Wh/liter) than LFP, but sodium-ion batteries have already improved since then.
OK, and where are the new numbers? 1% better, but still much worse than lfp?
Edit:a bit later they mention 175 Wh/kg and 10,000 lifetime cycles for some catl cells, that is not too bad, but still not great with lfp at about 200 Wh/kg which still is less than ~~Lithium Ion~~ NMC.
with lfp at about 200 Wh/kg which still is less than Lithium Ion.
LFP is a lithium-ion technology. You probably meant "worse than NMC", which is another, older, higher density but less safe lithium-ion technology.
Right, thanks. did not remember that name and searching yielded articles writing it like that so I went with it.
As bullish as I am on Sodium-ion batteries, only very recently did researchers figure out how to boost the charge capacity, making any attempted commercial models in use so far nice, but not the final form where normies are buying them from Home Depot.
The Sehol car mentioned is a niche configuration of a common model, because the Li-ion model goes farther between charges. Other than the launch in 2023, and articles recycling the same info, find me 1 article that doesn't use words like "could" or "will" or "might" about sales of this model? Same thing for the BYD Seagull with Na-ion batteries. It's all greenwashing news where if you dig at it even slightly, you see how not real any of it is.
It's closer than it was 5 years ago, but it's still not a "revolution" by any means.
This has got to be better than lithium mining.
Sodium ion is great, but
While batteries have enabled passenger car developments, they have been somewhat stymied in large mobile power applications like shipping and electric trucks. That day is gone now. At these costs, electric shipping is achievable and the debate over alternative fuels will fall off quickly as applications are realized.
heavy transport is not the right application. Very heavy, and LFP has similar advantages while only being medium heavy. heating vehicle batteries is a solved problem.
Great that you can get a home power 48v 33.6kwh system for well under $3000. (afaik, it comes with connector plates for 112x100ahx3v for $2340. Don't know about shipping or a box)
For 10% more, on that site, LFP is 33% lighter. Can affect shipping costs.
Sodium ion has extra applications/advantages. Not requiring a heated space could place them under solar panels in the field.
At $100/kwh or less, "retail", offgrid even oversized solar+ batteries is far cheaper than any utility service. At low charge/discharge rates (4+ hour charge from solar, and 16 hours of discharge (even with 0.25c peak discharge), 10000 cycles is achievable with both chemistries. $0.01/kwh/cycle.
The article has so many acronyms in it, I had to give up reading it. I assume this isn't just cat like typing?
I got a LIPO4 battery to run my tiny plastic boat or canoe with a trolling motor, most amazing performance I've ever seen. Hours of full thrust, never dropped below 20% power. So what's up with that tech?
No, it actually hasn't. It's also not any better than any other battery tech out there right now. Longer term but less volume storage is a trade off.
What happened to these Graphene batteries and capacitors we were supposed to have by now?
sodium-ion is better than acid-lead in every use case (theoretically, when the tech reaches maturity), unlikely to beat lithium ion and others for the high-capacity/low weight type stuff but far as cheap/environmentally safe batteries goes sodium-ion should quickly dominate the field.
Yeah, this kind of tech can actually be groundbreaking.
10.000 charge cycles? You can imagine lot's of new things with that. Maybe not a capitalistic quick buck but something bettering society.
Also for what I have understood it's wildly better than lipo etc when it comes to resource use, especially "rare" earth.
More durable, cheaper, can be operated at a wider temperature range and much safer, but at a cost of lower energy density.
They look like a big step forward for uses where density matters little, like grid energy storage or small scale home backups.
