"So far, the Sydney researchers have only created and tested lab-scale versions of their RT Na-S battery. They now plan to focus on scaling up and commercializing the tech, which will likely take several years."

It's not "cheaper" if you can't buy it.

GTFO with this battery which doesn't exist commercially and, based on the million other posts like this we've seen, never will. :(

[What’s new? Existing RT Na-S batteries have had limited storage capacity and a short life cycle, which has held back their commercialization, but there’s now a new kind of RT Na-S battery, developed by Zhao’s team. According to their paper, the device has four times the storage capacity of a lithium-ion battery and an ultra-long life — after 1,000 cycles, it still retained about half of its capacity, which the researchers claim is “unprecedented.”]

I'm sceptical. Li+ batteries have expected life of 500 to 1200 cycles, before dropping below 70% charge. The capacity could refer to useful energy though. Li+ can only be discharged to 70%, where Na chemistry allows for full discharge. The problem is that voltage drops with the capacity, so although you could use them down to 0% charge, they won't necessarily be useful.

Still, if they turn out functionally similar, a cheaper construction would be an advantage.

Many things are demoed like this much like at trade shows that never hit the market for whatever reason. In particular medical treatments.

Then just because its better does not always mean it sees the light of day. Hundreds of billions have been invested so that means you got a fight if you threaten that.

bring it to market and we will see how expensive it actually is

i just want to say my favorite story about vaporware tech is that we used to talk on forums all the time in the mid 90s about tiny hard drives much like we hear about batteries now

well, eventually a tiny hard drive hit the market and it was made into the first iPod amongst other mp3 players.

that directly led to the iphone. the iphone and etc basically changed the world.

my 2 cents. when it hits, it hits and we take it for granted

Yes, machine learning is another great example. Now that it’s happening, it’s happening fast.

I’m pretty confident that we’ll also get next generation solar panels by end of decade

imagine filling up your 6 year old car and only getting half the milage.

Yeah, I’m curious what they mean by capacity. Typically I hear batteries talked about in energy density such as kWh/kg or something. A MWh is possible with any chemistry by just having enough of them.

Imagine taking a finite resource that will take millions of years to replenish and which is rapidly making this planet less and less hospitable for organic lifeforms... just to fill up the tank of your 6-year-old car.

that’s not a bad argument - incomplete though. all of the electrical elements except the wire itself is not recyclable. at this level of technology a battery powered car has 1/2-1/4 the lifespan of an ICE powered machine with less reusable material. not a fair trade by any stretch yet.

the tech needs improvement still. i hope it happens soon.

The main ingredients are Sodium (one half of normal table salt) and sulfer, that we already have piles and piles of ever since we started removing it from our fuels.

We already have pretty good ways of taking any voltage input and returning a steady voltage. As long as the power requirements don't exceed the maximum Amp the battery will allow at the lower voltages that shouldn't be a insurmountable problem.

These articles suck. They put at the end can take several years to get a production ready version. Then why bother with the article at all?

Yeah, it’s been something over the last few months to watch people suddenly learn that AI is an actual thing and not just a marketing buzzword. Like yeah, dudes, if you were paying attention, things have been getting extremely wild for years now.

Ah yes, the weekly "new revolutionary battery has been developed"-post. Ive been seeing them for years, yet batteries have barely improved.

It still needs work. After 1,000 cycles it still retained half of its capacity, not overly great.

So in four or five years I can randomly remember this article and go, "Hmmm whatever happened to that 'new battery' we were supposed to get?" Probably gets bought by BP or Shell to be purposefully shelved like fuel cells and cheap electrolysis.

Any proof of this claim or is this just another pile of paranoid drivel from conspiracy kooks?
