The Dangers of Faulty or Mishandled Lithium Ion Batteries. - Skullmeat - 01-07-2016
Lithium Ion packs contain a lot of energy. If they fail catastrophically, the effects can be very dangerous, as this video graphically demonstrates. Never alter, modify, or play with lithium packs, and always buy quality parts, designed for your device.

Vouch, these are also the same technology as Lithium-Polymer (LiPo) batteries common in RC vehicles and such.
While they have safety features to prevent this kind of thing from happening, Li-ion batteries are not stable by nature, and can have their temperature run wild if they get too hot.
Basically, if you're using Li-ion/LiPo batteries, get name brand, follow safety instructions, and be cautious. I had a classmate in middle school who's father lost two fingers because the battery he was using overheated and vented flames.

I'm glad I read this thread. I have a powerful laser pointer which runs off a rechargeable lithium ION battery. Better be careful with it o.o

Cell phones, electric cars, etc all use Lithium Ion packs. They are everywhere in life. I've seen users do mean and nasty things to them, and it always scares the shit out of me when they do. It's one of the main reasons I remove the batteries from clients machines when servicing them.

With enough cells I could honestly see that making a powerful explosive.

Ehhhhh. The main problem with it as an explosive device is that while it has a large capacity for energy, even in the result of a catastrophic failure, as you can see in most videos, where the battery is usually enclosed in the plastic of the device it's in, its more prone to catching fire than it is at releasing its energy at once needed to have an explosive reaction. I suppose one could in theory trap the escaping energy until you create enough pressure, but those kinds of bombs have (in my opinion) not held up to raw material potential energy release (i.e. most bombs used).
Pressure bombs are excellent for shrapnel, but are generally unpredictable and sometimes unreliable (leaks, pressure puncturing the casing instead, etc)

Viewing the video, has been the best 5 minutes of my day.
I knew the batteries were dangerous, but not to the extent of the demonstration.

This is cool to watch, also why I always unplug everything I don't trust.

That's good practice.
I've actually been leaving my systems (lappies) powered-up whilst away from home for a long duration. After viewing this and It's potential dangers, I think I may save the sessions (hibernate or standby/sleep) and disconnect the adapters.

Disappointing lack of mixtape jokes. But while you can open laptop batteries and replace the Li-On batteries themselves (I've done this myself for older machines), DO NOT OPEN THE ACTUAL BATTERIES. Plain and simple.
Video of what I'm talking about (rebuilding a laptop battery pack):
