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.
Wondering why you feel that way? It would be easy to design packs of 4 that would have rotations where one cell does the resetting cycle while the others do the regular one? Is the reset cycle as long as the recharge one btw?
