ELI5: How do they manufacture batteries so that they give off power?

So power (in this case) = electrons moving from on place to another. So they take one compound that really wants electrons and another compound that has a lot of electrons to give away and they connect them in such a way that if you hook up the positive and negative ends, electrons flow to the first compound from the second.
