SUMMARY

This discussion focuses on identifying the most suitable ferromagnetic materials for use as cathodes in aluminum anode batteries, specifically with a sulfuric acid solution. The user is considering various ferromagnetic candidates, including Cobalt, Iron, and Nickel, while noting that the aluminum anode is an alloy classified as 6101. The goal is to empirically test the internal effects of these materials in a centrifugal cell design, akin to flywheel battery technology. The user seeks guidance on the best cathode options from the provided list of ferromagnetic materials.

This is a list of ferromagnetic materials that I've found on Wikipedia's category ferromagnetic materials page.

I was wondering which of these materials would make possibly great cathodes for aluminum anode in the application of creating an sulfuric solution based acid battery. The battery I want to design has centrifugal cells and I want to empirically test out this internal affect that it may have within the battery (similar to flywheel battery technology with the added chemical reaction effect as well).

I was thinking of a cobalt oxide but it's been a while since I dealt with a similar problem to this one so I can't souly trust my own intuition on this one. Any possible guidance will be greatly appreciated!

Here is the list of the possible cathode candidates that I'm searching for

Sorry, I forgot to mention that the aluminum anode that I want to use is an alloy of aluminum, specifically classified as 6101.
