Does anyone know if a tungsten-/copper+ saltwater battery have any significant charge if any? Willing to experiment myself, but don't want to waste money without asking first
This isn't right. Why do you think tungsten's oxidation and reduction potentials are different? It's just one or the other direction for the reaction. The temperature dependence of electrochemical potential is given by the Nernst equation:View attachment 258206View attachment 258207
From what I learned the potential of a Copper tungsten cell of is 0.457v, did I do the math right? or no? also believe my previous hypothesis is incorrect, as tungsten's oxidation potential would be increased at higher temperatures and it's reduction potential would be increased at lower temperatures, meaning I'd have to now reverse my experiment. Charge @ lower temperatures and discharge @ higher temperatures. Which doesn't make sense in any practical application.
