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

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?

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

Probably not the best idea to open a battery without gloves and a mask (though lithium batteries are worse in terms of gases). Still very interesting to see the electrolyte though.

The quantity and variety of things that I've opened up during my lifetime without 'gloves and a mask' would probably scare you very much. The worst mistake I made to date is grinding off the top of a BLY90 as a kid before I knew what a MSDS is. So far so good, I think these folks will be fine as long as they wash their hands afterwards before eating, cleaning up after you've dropped a fluorescent tube is probably a l…

I think one of the bits I liked most was "Romeo (Retired Old Men Eating Out) Club" - looking at its website it seems like quite a large thing over there. I know that my Grandma goes to something similar (restricted to just tea and bingo), but it makes me wonder if a similar organisation exists in the UK; a lot of the older folk I know just aren't very social any more, simply due to the fact that their social groups h…

One excellent organization is U3A http://www.u3a.org.uk/ My father runs one of their groups that specializes in studying geology, and they regularly have a hundred people turn up to the seminars they run. Science and social go well together when you've lots of free time.
