Flow Battery Research Collective

Ah, in the FAQ ...
Yes, was thinking wrong from other and not so good sources.

After I look around, I can't find much data of performance.

I take a look also in principes and now I know. I was wrong. I ever tought it is pumped from one side to other, but istn't.
So my diagram in the other thread is nonsense...

But, I think about the efficiency to totally mix it in one unstructured container on each side. My thinking here, it will press down the efficiency?

Is there anywhere a diagram of load and unload process?
Yes, you can optimize the cell but would think, also the storage management could be a factor to make the system more efficient.
So the unleaded flowing back could be a bad thing...?
A test with a really long pipe instead of big tubes/container could be a good idea for a better sorting of loaded an unloaded salt solution. So that not the fresh used stuff flows directly back and possibly damages the efficiency ot the cells work.
Eventually a leaded flow could do the trick?

If it is so, later could be used a cheap leveled grid into a tube the leading element for a flow in row.

So on load would be the goal to use the most unloaded stuff at first and on unload using the most loaded stuff at first.
But I'm not a physics expert for electrical poteincial, I only try to go a simple way of my normal logic.

Yes, seems I was thinking it wrong and have to read again.
Is it pumped everytime from and back into the same reservoir?

Oh, ok, think I misunderstand the system the whole time ...
Sorry! 🫣
... was also wondering about the two pumps...
So put the thread in the waste... ... it is nonsense ...

In the low pressure case also you don't need a special pump for salt solutions.
Also it's easily possible do run any cells parallel with only one pump.

I don't know, what pressure the cell needs, so I made both cases.

Hi, was observing this theme long time and also I've seen the problems.
I have made two sketches for a possible solution what prevent probmems of security and efficiency.
So the water filled capsuled system prevent too high wasting of energy by senseless level differences because the reservoirs can swim up and down. So you can in one case use level differences and in the other case you can prevent senseless level differences.
In small testing systems it plays not so a big role, but in bigger systems and it does and lead also to senseless pressure on the pipes.
Also prevent the setup any leakage of chemicals in this closed setup. On leakages on pumps or so, the chemicals flowing back in it's reservoir. Also the water does prevent leakages of the salt solution outside of the box.
Also electrical elements are secure because all can be installed above the chemicals ways.

This are only sketches, but eventually helpful?

Hi, I'm long time a observer of this theme and frustrating about complicated thinking and crashes of developing companies behind. It's mostly a too complicated thinking behind.
I'm happy to find this open source community, open for many users to think about this important technology!

Sorry for my not perfect english anytime!
