    DOE Grant APPROVED... Ni-Fe test at National Renewable Energy Lab (NREL)

    Dear Solar Panel Forum,

    I have been asked to design a series of tests that will help determine (once and for all) the actual performance characteristics of the Ni-Fe battery. Today I am asking for your help to design the Nickel Iron Battery Test.

    Thanks to a generous State and Federal grant, this test will be carried out under controlled conditions at National Renewable Energy Laboratory (NREL).

    Based on previous input, I have identified several important issues including discharge rate, charge efficiency, and overall performance given very high and low temperatures.

    The draft project plan calls for testing various cells at the 2, 5, 10, and 20 hour discharge rates and at temperatures of -40

    Well, the 20 hr test is more important to me than the others. (but I guess utilities are interested in the shorter timeframes for peaking)

    Also, some sort of test regarding "float oil" on the surface (seal off Co2, prevent carbonation) seems like it would be useful.
