Crystal Cell Research for Experimenter

I have found that there is an equilibrium in anode and cathode sizes where if you increase the anode size and not increase the cathode size the total current reaches a point where the size is no longer beneficial. However increasing the cathode size and not changing the anode size will double and triple the total current in comparison.

But on the topic of materials I have found the more conductive the anode material is the higher the amperage will be. But the voltage is usually limited to its galvanic potential

As an example mg is -1.50
where aluminum is -1.0
and gold silver and carbon (graphite respectively) is +2.0

It all really boils down to its  internal resistance and potential (respectively)

I built 21 ibpointless2 batteries on a piece of wood about a year ago to test the inconsistencies in the builds - what worked better and worse. From my notes after testing and dissecting them "cathode and anode further apart worked better" - if you look at the DiveFlyFish video, you will notice that the smaller cathode was further away from the anode and that could be the performance difference and why it shows much more resistance.

The problem with building cells to be used together is that it's near impossible to get them exactly to specs, so I tend to go with single cells and tune them to the circuit I am using, or visa versa. Here's a fun pic of the beginning of the build of the 21 ibpointless2 batteries! - teo

Cool test there. When you have the distance between the poles, do you have more electrolyte also?

Not necessarily, but my notes suggest more electrolyte was better. I think that would be a good test.

I think graphite and magnesium would be an interesting test. I haven't done that yet... see...
