China's new iron battery hits 99.4 percent efficiency over 6000 cycles

A research team at the Institute of Metal Research of the Chinese Academy of Sciences (CAS) has advanced "all-iron" flow battery technology.

The actual story buried at the end of a Sino #1 article-

In the United States, companies like Oregon-based ESS Tech Inc. are already deploying iron flow systems for tech giants like Google.

However, some of these existing designs could struggle with “dendrites” — tiny, needle-like crystals that can short-circuit the battery. The Chinese team believes they have leapfrogged these hurdles by using an alkaline-based chemistry and their new molecular “shield.”

Revolutionary new battery idea that will overtake lithium ion huh? Throw it on the pile

For grid-storage they may very well be…
https://en.wikipedia.org/wiki/Iron_redox_flow_battery
is e.g. in place in Sacramaneto, CA with a storage of 2 GWh and a maximum power of 200 MW.
For grid-storage durability and ovrerall cost efficiency are more important than energy density so I expect redox flow batteries to overtake lithium ion based batteries there.

I’ve seen this article every two weeks for the last 15 years.

Ehh I follow the battery news well enough to know it’s different this time.

The way you can tell is that it isn’t coming from the MIT press release department.

Honestly, it’s a good time for batteries and solar panels.

I think we’re just going to let out current infrastructure rot out from under us and while house generators run on gas.

I mean, we could modernize our infrastructure, but we can barely keep bridges standing and I’m not sure if utilities are communism or not. I suspect that they are.

The lithium iron phosphate is already pretty impressive, just a bit pricey.

Anything “flow” is going to be game changing to an extent I think let readers really barely understand. It turns energy storage into something as boring and understood as the refrigeration cycle. Flow means storage at scale becomes trivial.

Meanwhile the US has a president who doesn’t understand how magnets work.

To be fair, neither do i. Or probably most people. But he fires people who do.

Kid Rock is working on a new battery. Game changer.

Hook a generator up to Republican flip flopping hypocrisy, and we could power the universe.

But at what cost?

Iron batteries are big and heavy. Not good for portable applications.

Less?

Ooohhhh revolutionary battery article #15592508

I’m sure this one won’t be bullshit and will come into production tomorrow, right?

You seem

This is just a shallow, cynical, anti-intellectual remark.

Sodium ion batteries are already hitting production.

Iron flow and vanadium redox batteries also already exist in the real world.

Grid and residential battery installations are happening at a rapidly accelerating pace.

Lithium ion battery prices have dropped something like 90% over the last 15 years.

Battery technology is improving at dramatic rate, both lithium ion and non lithium ion solutions.

the article literally links to how BYD is putting this stuff into production https://interestingengineering.com/energy/catl-ev-battery-7-minute-charge

Sounds heavy

Not a problem if these are used for grid storage.

Or ships.

Hah ok

Weird how China is always inventing things that already exist.

It’s almost like all they do is copy others.

These types of batteries have been in use for a while they’re just not that common as they take up a LOT of space, and there are better options that use less space.

They seem to have tackled the issue of dendrite forming.
That would reduce maintenance on iron redox flow batteries sigificantly if true.

So you did not read the article. At all.

Spamoflage

I’m starting to see that China may have a large presence on lemmy. It would make sense with the .ml groups. You can see a lot of pro China stuff here plus lemmy is a generator against things like AI which benefits China.

If people who enjoy futuristic tech and hate AI slop are now on the side of China, sign my ass up

I think they are. I think tech forums are essentially places to convince people to hate tech. Hate progress. Meanwhile other countries embrace these new technologies and develop, build and iterate.

If you don’t want to see so much China and Russia-glazing, just block yogthos and jackeroni, that should cut it down about 40%. I personally don’t mind agendaposting because I can tell from the get-go who it’s coming from. There are prolific anti-China agendaposters too, for example from an account named Scotty.
