What's the term for when 2 elements have more potential to make power in a DIY battery?

I'm investigating materials to use in DIY batteries. DIY batteries sometimes use copper and zinc electrodes. Copper has a greater positive "potential" and zinc has a negative "potential", and when you add up the absolute value of these potentials, yout get a number. The higher the number the more power the battery will generate, and that's why we use lithium in batteries.


What is this term called? I googled "electric potential" and "electrochemical potential" and it does not seem to fit what I'm looking for.

I'm actually looking for a table of elements which describes the differentt potentials for the anode and cathode. Once I have a decent anode/cathode set, I'll experiment with different electrolytes and post results for voltage, amps, and runtimes for different combinations.

Thanks!

I found it. It’s “electrode potential”. “Standard electrode potential - Wikipedia*“:Standard electrode potential - Wikipedia*(data_page)
