Exploding batteries: I thought this problem had been solved long ago
I remember that some of the first lithium batteries caught fire spontaneously, but that was ten years ago. How come we still have this problem?
|
We still have the problem because it's part of the technology -- put that much chemical energy into one place and you've made a bomb, in a sense, so there's not a lot that can be done to make it less likely to explode. Any solution is likely to lower the energy density so make batteries bigger and store less power.
The above is overly simplified but, to my mind at least, is the essence of the problem. |
If airliners can burn, I guess notepads aren't likely to be exempt. Small/compact == dense.
Dense inflammables are always a worry ... |
Also the rate of charging is important.
In the race for market share, many chargers use "fast charging" which tends to screw up the battery. Read below for more details. third party chargers are labelled and sold as fast chargers. http://www.bbc.com/news/technology-37255127 An excerpt from the article. Quote:

Yep and I was considering getting the Note7 , guess I'll have to wait a while now...

The element Lithium, when exposed to air, burns explosively. Search YouTube for "lithium fire."
(The element, Lithium, when exposed to war, burns for 15 years ...) :mad: |
since it was a programming forum:
how many times will be the same (coding) error detected and fixed? (countless...) |
Agree. The problem is not fixed people attempt to address by regulation and design, however given the largeness of the business world, it is very possible to buy dangerous batteries and further attach them dangerously to products. We used some very good 850 mAH LiON batteries, however in soldering leads to it, one of our techs shorted it by accident and took the load across his thumb. Very bad burn.

Because lithium-ion batteries are dangerous and they will not easily be made safe. Lithium iron phosphate less dangerous.
I got a talking to by TSA at the airline room about lithium batteries last year. I said that yes, I did have lithium batteries and showed them my phone. Guess it's OK as long as it might catch fire in your pants was the final answer. |
There was an article on The Register about this very topic today, with a little information (not a lot but still interesting).

They may end up having to require them to be placed in some sort of fire resistant container if things keep going.

The Register explores, in the usual Register style, the mechanics of why batteries explode:

The expert said this. "Transportation of lithium batteries is also no longer allowed on passenger aircraft," Oliver said."
Guess my phone doesn't know that. |
I've read about that. I can't provide a citation, but what I read is that those phones are supposed to be off, not that they can't be carried on the plane at all.
(The last time I was on a plane, all cell phones were required to be turned off anyway. After 30 years as a road warrior, if I never get on a plane again, it will be too soon.) |
Transportation of lithium batteries in cell phones on an airplane is one of those risks that has to be taken, because everyone has a phone in their pocket ... or in their luggage, as the case may be. If you tried to forbid them being carried on an airplane, no one would fly.

Ought to bring some sand.
