What would the inside of a recharged battery look like I wonder.

It's not the same technology and I wouldn't recommend tearing a lithium battery apart to look inside. Actually, I wouldn't recommend tearing apart any kind of batteries, lots of nasty stuff inside. You can find plenty of videos on youtube showing you the process, for instance: https://www.youtube.com/watch?v=BliWUHSOalU https://www.youtube.com/watch?v=BliWUHSOalU

  After watching that it made me think that lithium batteries could be turned into a weapon on a plane by terrorists. Assuming that they are that easy to accidentally short them out. Should they not be a banned from being taken in the cabin?
  - TazeTSchnitzel 12y ago
    They'd probably ban them if people didn't want to use laptops and phones.
  - iamds 12y ago
    It's probably not banned because someone who could take over a plane with a lithium battery could take over a plane without a lithium battery.

      But someone who could take over a plane with a nail clipper could probably manage without it, too.
      - kd0amg 12y ago
        And the TSA allows nail clippers in the cabin.

      Batteries above a certain capacity are not allowed. http://blog.tsa.gov/2013/06/travel-tips-tuesday-safely-packing.html http://blog.tsa.gov/2013/06/travel-tips-tuesday-safely-packi...

      Any idiot could use one to set a plane on fire.

    What makes you think banning in-cabin items has anything to do with actually making air planes more secure?

    > After watching that it made me think that lithium batteries could be turned into a weapon Lithium batteries have vents, so they don't explode they just "phhuut".
    - goodcanadian 12y ago
      Vents can be blocked if you are trying to make it explode . . .

    The USPS has already banned shipment of lithium batteries overseas because of suspicions of battery fires in flight causing cargo jet crashes. When it was first created, the ban included devices as well as just solo batteries but it looks like that has been loosened.

    The funny thing is that in the US you're not allowed to have loose lithium batteries in your checked baggage, but you can carry them on the plane.
    - benjymau5 12y ago
      Many airlines also wont allow shipments of lithium or things containing lithium batteries on passenger flights. Apparently they have a habit of spontaneous combustion. So shipments of iphones have to be specially packaged and sent on cargo flights.
    - goodcanadian 12y ago
      If the battery spontaneously combusts in the hold, you have a serious problem. The fire will be quite large before anyone knows about it. If your laptop catches fire in the cabin, you'll probably scream immediately, and they have burn proof fire bags to shove the laptop into.
  - fnordfnordfnord 12y ago
    Yup. Also, don't forget about what small amounts of Mercury https://www.youtube.com/watch?v=Z7Ilxsu-JlY https://www.youtube.com/watch?v=Z7Ilxsu-JlY or Gallium https://www.youtube.com/watch?v=Z7Ilxsu-JlY https://www.youtube.com/watch?v=Z7Ilxsu-JlY could do. Happy flying!

    They aren't really that easy to weaponize, at least not any more. The earliest kinds of Lithium cells actually contained elemental lithium, and could easily cause fire or explosion under certain conditions. Think the Dell laptop fire batteries. Lithium _Ion_ batteries produced today are newer designs which use an intercalated Lithium compound (usually with Cobalt, Iron or Manganese) which greatly improves the stability of the battery while under stress. Further to that, pressure venting is almost always incorporated into the canister enclosing the cell, allowing it to depressurize in a safe manner similar to capacitors. That's not to say they are totally safe - all batteries require a great deal of care and not all Lithium batteries incorporate these safety features. The pouch cells used in RC aircraft, for example can catch fire fairly easily due to their lack of a strong outer shell, their extreme power density and lack of any protection circuitry. These are heavily regulated and you would not be allowed to take them in your carry-on, and all Lithium Ion batteries over a certain Wh rating are similarly controlled.

      > [RC pouch cells] are heavily regulated and you would not be allowed to take them in your carry-on Speaking at least for Canadian airlines, you're incorrect - I asked ahead, and was told that I could bring them, but _must_ have them in my carry on. (and protect the connectors, etc.)
