[NewCandle] Aluminum-iron battery

[Keith Nagel]

Hey Horace,

I suppose it's like a very dilute raney nickel. The iron
would tend to accumulate at the cathode spot, just by virtue of
the fact that the aluminum is preferentially dissolved by
the salt water. Unlike the raney nickel, the iron is
somewhat soluble in the chloride, so the potential difference
would be lessened a bit.

Given the accumulating iron on the aluminum surface, an explanation  
of the corrosion might be that an iron-aluminum battery forms.  The  
current increases as the aluminum erodes and the iron accumulates on  
the surface and in solution.  The current is made stronger at all  
points by making the gap between foil surfaces smaller, by thus  
reducing cell resistance.

Best regards,
