I’m going to need to see evidence of this because China has been making numerous bold claims of what it produces, but they don’t go into that much depth or has developed anything to demonstrate that claim.
It’s not like scientists in China had just invented it.
Yet they seem to have improved the tech, especially around the forming of dendrites at the cathode.
If you want proof that the tech works:
a grid-strorage of the iron redox flow type has been installed in 2022 by ESS and Sacramento Municipal Utility District in California: https://www.smud.org/Corporate/About-us/News-and-Media/2022/2022/Accelerating-decarbonization-ESS-Inc-and-SMUD-announce-agreement-for-long-duration-energy-storage
China has also been delivering, so I wouldn’t bet against them.
A notorious example is Tesla, when they adopted the lithium-iron-phosphate batteries made by CATL because they were cheaper, safer and easier to build (no nickel or cobalt required).
Of course some of these articles are pure hype for vapourware, but this one’s sounding plausible - they claim to have engineered a structure that is negatively charged, while also physically preventing electrolyte crossover, and that this prevents degradation by two orders of magnitude.
It’s not preposterous, and might be enough to make these batteries usable on a massive scale…
As I wrote in other comments here in this post, the tech is not exactly new:
https://en.wikipedia.org/wiki/Iron_redox_flow_battery
and it is e.g. in place in Sacramaneto, CA with a storage of 2 GWh and a maximum power of 200 MW.
Apparently it’s working and just need to be scaled up.
They don’t just need to work, they need to be economically viable.
These batteries have active components, since they actually pump the electrolyte, and there’s a fairly substantial level of degradation and corrosion, along with leaking across the membrane that leads to loss of capacity over time.
If some of these problems can be reduced (like the article claims they do) then they’re even more attractive.
I really hope this helps with massively expanding renewables storage, because that’s bastion holding up fossil fuels in electricity generation, and it will allow shutting down all those coal, gas, even nuclear plants!
i just completely ignore all news about new battery technology, i seriously do not see the point in paying attention until it’s actually available for purchase and people have tested it in real life.
This is targeted towards industrial needs so I doubt it’d be available for consumer purchase (, just industry purchase).
