I am a retired man and seek for activity. I dont have background in chemistry but I want to learn an aluminum battery..the known problem is my aluminum metal get eaten and also corrosion even if using sodium electrolite and worse if using Aluminum chloride.
So I just try PAC for water treatment and it look like the reduction is minimum. But as usual the usual voltage drop always problem in any set up of galvanic.
What happen and how to prevent that? my experiment setup is a square aluminum that act as a case also as cathode. Fill with carbon powder separated by paper. in the center is a graphyte rod pour with PAC in water...this gives a 2,5V
please review what kind of chemical formula during equilibrium and during recharge? why voltage is droping or how to make this setup more better and stable as battery?
