Vanadium Flow Batteries could be the future once economies of scale make them affordable etc.

A 48v cell allegedly can power a car up to 300 Km/h and has a 1000 mile range, suffers no memory effect and can be cycled repeatedly with no loss of capacity.  All this in the size of a suitcase.

Clearly there is some marketing hype involved in the above but the technology does exist in much larger units for storing renewable energy.

 

 

That link is a masterclass in marketing puff. The front page tells us NOTHING about what they are, only how great they are.

I didn't explore the links at the bottom as I doubt I'll find much differerent. Besides, I have to go out now

Indeed - however, like I say, the technology is sound and employed elsewhere.  Just need to see it in action on the smaller scale

So if I get two plastic dustbins and fill one with dilute sulphuric acid what else do I have to do...?

I have some chrome vanadium spanners, are they any use?

Thanks for bringing this to my attention. I had not heard of this type of battery before.

Here is a technical rather than marketing hype based description.

https://en.m.wikipedia.org/wiki/Vanadium_redox_battery

It says the energy density is poor compared to other rechargeable batteries and the battery is limited in its temperature operating range (10-40°C) but capacity is only limited only by the size of the electrolyte tanks.

There are several already in use in fixed applications (UPS's etc) which is promising. I await further developments with interest.
