I want to build a salt battery, and I've seen them use Zinc and Copper. But what if I replaced Zinc with Tungsten, since it has an ion charge of 6+. Would that increase the amount of ions, released into the water, and increase the power output? Do you have any suggestions for more potent materials than zinc and copper? Any other material I could use to dissolve ions from a metal into water? I don't mean an acid.
