How a Battery Works?

  1. Mar 28, 2015 #1
    So I understand that a battery consists of an anode, cathode, and electrolyte.

    Question: What is the function of the electrolyte? Can we use a conductor instead of an electrolyte like some kind of metal? If so, why don't we?

    Now for a penny and nickel battery stacked on top of each other you have a
    penny, electrolyte (wet cardboard), nickel, penny, electrolyte, nickel, etc.
    I have three questions:
    1) Why is there no electrolyte between nickel and penny? (Look in the middle and you'll see what I mean)
    2) Will it work if there was an electrolyte there?
    3) Will it work without any electrolytes between any of the pennies and nickels?

    Thank you for responding.

    I didn't realize it has to do with the chemical reaction.
