      Litium is extremely toxic. And the energy density in an average laptop battery is enough to bring more then enough of it in the air.

      The scary part is that got allowed on board of airplanes after the FAA got convinced that correctly operating bateries are safe. Well... This brings up the obvious question - what about incorrectly operating ones. And what about ones that have had their short circuit protection removed?

        Lithium is toxic, but only in huge amounts and, more importantly, only after a long exposure (weeks). It is used in the treatment of certain psychiatric disorders, and it isn't unusual for a patient to receive several grams of lithium daily. A short-term toxic dose of lithium is probably contained in about 20 or so batteries, and only assuming you inhale ALL of the fumes resulting from their explosion. Not likely to happen.
        • Err... I beg to differ sir.

          You are mistaking the lethality levels for mildly toxic lithium salts taken orally with the lethality levels for various compounds (including LiOH) coming from combustion of lithium ion batteries. Besides some of them having a much lower LDA50, they will also be considerably more dangerous because they will be inhaled.

          • Okay, in that case nickel batteries are even worse - they can also explode, and contain KOH, which is a stronger base than LiOH due to the ionic radius of potassium... :)
      • If they banned LiIon batteries on planes, hoards of irate businessmen would become more of a nuesance than any terrorist threat. And you'd probably have to have a lot of the batteries to fully saturate the air, and I don't think anybody would risk it enough to make a bunch of passengers nautious.
