Design of zinc bromide flow battery (discuss.tchncs.de)

This type of battery seems quite easy to DIY. Cheap materials, relatively safe, not flammable.

You can either maken individual cells or make a flow battery which is theoretically infinitely scalable. You'd be limited by the size of the electrode in how much power this battery can deliver.

Has anyone here tried to make a flow battery? And did you have any success with powering something large and energy consuming?

I guess it would also be possible to make a battery out of old buckets, carbon fiber mesh and separator material such as glass fiber.

Lmao, do you drink your Li-po batteries as well?

The typical dose needed to reach bromism (when talking about old bromide sedatives) is 0.5g-1.0g a day, the lethal dose of zinc bromide is 3-5g, those levels are not passive exposure levels, they're intentional or very unlucky accidental ingestion levels

Haha, I take your point!
