Lithium Ion Battery Explosion

Two lithium ion batteries exploding due to overcharging. This isn't to show that lithium batteries are unsafe. I just got bored and decided to blow up a couple cells from an unused battery I had lying around by removing their circuit protection. Explosions are a lot of fun.

cool. And I really like the look of the device at 12 seconds! Of course function trumps looks, but what is that thing? Or special voltage supply that is settable? It reminds me a little of some Fluke volt meter or something. But it must be a charger of some type, I'm guessing..

@rfsent5 That device at 12 seconds is an Omega temperature meter. The important measurement on the display is in the lower right hand. It shows the cell temperature. This was just for added entertainment (yeah, I know "Wow! Temperature readings! Exciting....not!). The loud humming you hear in the background is the DC supply I'm using to overcharge the cell.

I'm glad you didn't film the whole 25 minutes :)) Suspensful action minus the action part :D

@Hesam0000 I could have entertained you with song and dance, but I'm not that charismatic. I could have made it like an action movie: people in the foreground having fun and then an explosion happens in the background. "Whoa! Duck and cover!"

Did the second explosion actually destroy the glass box?

[celticrequiem]

@eggroll9000 Neither explosion did any damage to the box. It was actually a fume hood with a plexiglass viewing window. This is actually one of the more violent li-ion battery explosions I've experienced. Most others go off like a bottle rocket: the batteries heat up and expand until the pressure is released at a single point and fire and sparks are emitted. I've seen cylindrical batteries literally fly around like rockets, but there usually isn't a lot of force provided in the movement.

@grubbytron I prefer to do it at gas stations during rush hour. You know, to give people a show after a hard day at work.

@Adrian51524 I was really nervous filming that. That's why I jump after the first explosion and I laugh at myself :)

loool HOLY SHIT!

Just wanted to know...my cell phone battery is slightly bloated/puffed up, is it safe to continue using it or is there a risk of such an explosion?

what happen when you put a magnet against the lithium ion battery?

[Hesam0000]

@celticrequiem No, but you could've just wrote "Watch from time.... to time...." to avoid the no-change time.
