Searching for best ferromagetic cathode for aluminum anode battery

  1. Nov 4, 2014 #1
    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.

    Chemistry Data : [top]
    Aluminum................Balance

    Boron......................0.06 max

    Chromium...............0.03 max

    Copper....................0.1 max

    Iron..........................0.5 max

    Magnesium..............0.35 - 0.7

    Manganese..............0.03 max
    Remainder Each......0.03 max
    Remainder Total......0.1 max

    Silicon.....................0.3 - 0.7

    Zinc.........................0.1 max


    And the cobalt wont be an oxide because it is a cathode, so a cobalt oxide I know wouldn't help.
