John Burpo]] Though some nice micrographs like what you can find on the front page of this module would be great, your TEM results may have revealed nanowires that are not uniform in their appearance or in their gold coating. Fortunately, even ugly-duckling nanowires may serve beautifully when assembled into a battery. The question you'd like to address is if a battery electrode made from gold nanowires (+ some percentage of silver) performs better than a battery made with a solid, gold foil electrode. And having included silver in the templating, how does the % of that metal affect the voltage potential and the charging of the battery? To answer these questions, you will assemble your nanowires into a battery, mixing a known percentage of the active nanowire material, with a small amount of conducting material and a small amount of binding material. The conducting material we'll use is a graphite carbon called | + | [[Image:CoinCellAssembly.png|right|thumb|400px|Figure from Lt. Col. F.
