Chemistry of a Simple homemade battery

  1. Apr 2, 2010 #1
    I want to make a simple home made battery. I am just starting to do experiments at home and I have read you can make a simple battery from coins like pennies and nickles. In between the coins would be a wet paper towel soaked in salt water which acts as the electrolyte between the two coins. I know that the current is produced by oxidation reduction reactions, the problem is I do not remember enough Chemistry to go through the exact process! (Which I hope to fix soon) If someone would be able to go through the reactions of this home made simple battery that would be great! I like to completely understand something scientifically before doing it experimentally.
