Sorry, it still has a lot of improvements to be done.
This article uses “nano” way too much for me to take it seriously. It is written like a marketing piece.
Nano desu
Flow batteries are great for long duration storage, but not good for high power delivery.
This means they will work far better as grid storage than as EV batteries.
The article is about advancements that are solving the density problem.
What is your source?
High power is a matter of scaling (and size/space constraints). To increase the power output, the membrane size can be increased or multiple power cells can be installed as explained in the article:
If you want to store more energy, just increase the size of the solution storage tanks or the concentration of the solutions. If you want to provide more power, just stack more cells on top of one another or add new stacks.

Lithium batteries scale power and capacity at the same time. Flow batteries can scale power and capacity independently.
The advantage of flow batteries is that they can have enormous capacities without the added cost of upgrading the power, making it ideal for grid scale storage.
Even if this new flow battery reaches the energy density of a lithium battery, and can output sufficient power, it would still need to reach price parity to be competitive.
Lithium batteries are an ecological nightmare and I can’t wait for better technology
What makes a lithium iron phosphate battery an ecological nightmare?
If it still relies on mined lithium, it’s some pretty bad stuff. Come to find out mining isn’t super great for the environment.
Much of the lithium is mined in Australia or via salt brines in Chile.
It’s not worse environmentally than the other mined materials that go into a vehicle.
That doesn’t make it a good thing.
Ok so let’s drill into it further.
Lithium gets mined once and then enters a circular system where batteries can be recycled after 10+ years in service.
It doesn’t exist in isolation either. While lithium is mined, its competitors (oil, coal, gas) are too with significantly higher environmental costs. They’re also not reusable.
Zinc Bromide flow batteries look like a great idea for static energy storage but if you’re worried about mining, I have bad news.
Are lithium batteries getting recycled? Because there are millions of pounds of disposable vapes that just get fuckin yote directly into a landfill. Then they crack and leak PFAS into the ground water.
Large car batteries can become second life static energy storage before being completely recycled .
This is one of those instances where capitalism helps us out - there’s money to be made in old batteries.
Single use vapes are pretty damn disgusting all around TBH.
So we should continue mining single-use hydrocarbons because disposable vapes exist?
But it does mean it isn’t any worse as well. Plus lithium can be recycled.
Cobalt: https://earth.org/cobalt-mining/
There is zero cobalt in a lithium iron phosphate battery.
Is that the most commonly used type of batteries in EVs?
I’m not sure on the global percentage, but they’re becoming far more common. Most of the top selling EVs where I live (Tesla Model Y/3, BYD Atto 3, BYD Dolphin, MG ZS EV) all use lithium iron phosphate (LFP) batteries.
They have a somewhat lower energy density so they’ve been avoided, but they’re way safer and better eco wise to the point that they’re getting uptake
This is irrelevant. First, there are chemistries not using cobalt, as explained already. Second, elemental cobalt is infinitely recyclable as all elemental metals, thus we don’t need to mine that much more, just like we don’t mine as much iron ore as we did centuries ago (relative to overall consumption). Yes, we still mine a lot of iron ore, but we recycle a lot as well.
This cobalt must be mined first to be recycled later, and being infinity recyclable doesn’t mean it will be, for example if it’s cheaper to mine new cobalt instead of recycling.
It was already mined, it only needs to be recycled if we continue using old battery chemistries. Which is unlikely.
I’ve always hoped so. Finally deal with both range anxiety and charging time together.
That’d be cool.
Hydrogen solves that.
Hah, no. Storage and infrastructure are still non-existent. And low temperature operation is still an issue.
There are challenges, but Toyota is throwing their weight behind research on hydrogen ICE. Here’s a good summary and analysis video. Of course it’s not perfect, but they proved it can be made. Now it needs to be made more robust.
What Toyota is doing isn’t a good indicator. They’ve been at hydrogen for decades. And they are the single biggest laggard for decarbonizing transportation. That’s not even an opinion, that’s just facts about their lobbying and marketing. No amount of research will make hydrogen infrastructure appear.
Infrastructure comes following the demand. It’s not like there were gas stations before there were cars. On the other hand, I think it’s good they are investing money in different technologies. I think they realize whoever gets to the new solution first will reap benefits, kind of how Honda insisted on using 4-stroke engines in their dirt bikes while everyone else was pushing 2-stroke. When the 2-stroke ban came, everyone else struggled to switch while Honda had it perfected.
Toyota might be lobbying and pushing their solution, but as long as they are investing and solution is cleaner we benefit in the end. Certainly better than what oil-lobbyists are doing pushing the idea it’s not a big problem yet.
How do you drive demand? If there’s no infrastructure you can’t sell anything that relies on said infrastructure. How’s California’s Hydrogen Highway doing? Not good. Demand and infrastructure go hand in hand, and you can’t magically make one develop without the other. Thinking otherwise is merely wishful thinking.
Demand and infrastructure go hand in hand
This is what I meant, they drag each other.
make car battery big, use nano liquid, issue fixed?
That’s some crazy battery technology. This would greatly solve a lot of current issues.
