The guys at Flow Battery Research Collective have been designing a Redox Flow Battery development kit that you can build yourself using a 3d printer and a few tools. It’s a desktop size flow battery that you can use to either do your own research, e.g. on different electrolytes or just to replicate their experimental findings.
Redox Flow Batteries have the potential to become grid scale or home electric energy storage solutions that are way better for the environment than current lithium based batteries. They can often scale power and capacity independently and allow for repairs.
The FBRC project wants to spread the knowledge on RFBs and help kickstart a global community that develops sustainable energy storage technology in an ope source fashion.
Beware that the project is still in its infancy and sourcing the materials can be a bit of a challenge. Be sure to ask around in the forums for help!

I’ve always had a problem with peristaltic pumps. Given it’s all electrolyte, would other tech like MH be possible?
Interesting project! I will have to give it a look.

Any more details here? I’m guessing the necessary material for electrolytic and what not? Do you know about the boring adjacent stuff like measuring (eg how accurate do the measurements need to be, how precise, etc), disposal, etc?
You need Polypropylen filament for printing, graphite felt as electrode, grafoil gasket material as bipolar plate, brass plate as current collector (cut by cnc), silicone gasket material and a measurment device like a potentiostat.
If you’re really interested, living somewhere in the EU, I could send you some stuff. I also have the chemicals in big quantities.
Why brass and why a thick plate of it? I’ve designed and built RFBs; we played with aluminum ‘sticker’ sheets on some rigid backing and it worked fine.
