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.
Hmm I didn’t notice the resetting part yet. That is indeed very inconvenient and not something I’m willing to build a system for.
Perhaps just individual cells is better in that sense. My goal is a set and forget style battery that only needs maintenance in a few months.
