How to build a powerful single celled battery

  1. Sep 16, 2010 #1
    Hey guys, I'm new to this forum and I've been meaning to start a project of my own. I want to create a homemade battery that gives me the highest voltage and current I can have using only two-three metals and an electrolytic solution. It can only be easily accessed metals, as I live in a city and my biggest provider for materials and such is "Home Depot." Is sulfuric acid the best solution to use for this? Is it best to just go with a lemon battery instead? Thank You, I appreciate any help!

    Try aluminum-air batteries:

    How would that stand compared to a citric acid battery?
