Transcript of "Batteries"

  1. 1. BatteriesScott Brons
  2. 2.  Batteries are found everywhere! Found incell phones, computers, cars, ect. They have many sizes, shapes, andfunctions. Each have a specific purposealong with pros and cons.QuickTime™ and adecompressorare needed to see this picture.QuickTime™ and adecompressorare needed to see this picture.QuickTime™ and adecompressorare needed to see this picture.
  3. 3. How It Works What happens in a battery is this: Electrons go from the positive anode to thenegative anode creating a circuit. On their way, they can pass through a wireto a light bulb (in this example). The electrons pass through giving the bulbelectricity.QuickTime™ and adecompressorare needed to see this picture.
  4. 4. Dry-cellThese batteries are the most commonand probably the simplest. We findthem in appliances, remotes, and othersmall items.These batteries are what completestheir circuit and begin the flow ofelectrons.
  5. 5. Car BatteriesQuickTime™ and adecompressorare needed to see this picture.QuickTime™ and adecompressorare needed to see this picture. These batteries are abit more complex. They actually consist of6 batteries. Each generating about2 volts. PbO2 + 4H+ + SO4-- + 2e->PbSO4 + 2H2O Pb + SO4-- -> PbSO4 + 2e- Those are redoxreactions!!
  6. 6. Lithium-Ion Batteries Found in laptops or phones. The anode in this type is carbon, which isnot unusual. What defines this type is the cathode: it ismade of lithium cobalt oxide. They are made of this because lithium canhold lots of energy in atomic bonds. Pros: lightweight and efficient. Cons: very sensitive to extremetemperatures, more expensive, and if failingthey combust.
  7. 7. Implications. Why should we care?Batteries are everywhere. Wherecan we find them?The other option is either gasor electricity.Surrounded by these inventionsthey directly impact oureveryday lives.
