Li-ion tamers: Boffins build battery with built-in fire extinguisher Researchers at Stanford University say they have developed a method for building fire-extinguishing materials into standard lithium-ion batteries. The nine researchers behind the paper to be published in the journal Science Advances say that by packing flame-retardant triphenyl phosphate (TPP) into the battery pack behind a …
I wonder, does mentally adding some fluorine when seeing a formula of a phosphor-organic compound count as a thought crime... Probably I should stop wondering, I already hear the sound of black helicopters outside.
On a less humorous note - I frankly have some doubts about "low toxicity" of anything which has phosphorus and organics. Probably, it is because I studied chemistry when we had the VX family as a part of the "toxicology" (freshly renamed from "chemical warfare agents") course. Thankfully, it no longer had the lab part (*).
(*) You make only one mistake when synthesizing this stuff. It is usually your last
You've probably seen this before, but I still find it funnier than I should.
Unfortunately, the people of Boston, Massachusetts might have a comment or two about "the worst thing that can happen if you misuse a pressure cooker." Granted the original XKCD question specified "in a kitchen" but still...
Slightly tongue in cheek, but here goes ..
1. Mobile devices will get heavier, thicker
2. Devices will require their annual servicing to test the extinguisher.
3. Don't fire extingiushers need to be replaced after a number of years - so built in obsolescence - on safety grounds of course ..
4. If you phone goes off, then the person sitting next to you will think you are setting off some form of chemical device, so you'll get punched, shot or worse !
5. Can you really carry pressurised canisters in hand luggage on planes ?
Not actually a fire extinguisher.
More like the special expanding foam fitted behind light fittings in modern buildings that expands to cut off air flow in crawlspaces.
Not tested but only good for 1 use.
Sounds like a pretty good idea as power density is (slowly) going up.
Electrospinning. Is there no end to what this technique can be used for?
actually, the first thing _I_ thought of was LiPo batteries in aircraft [which a couple of years ago grounded 777's for a bit, as I recall] and electric cars would be the next in line. So yeah.
"what happens in a car crash" with electric batteries in every exposed area of a car? Hopefully NOT a class D fire, but that happened once already, and I remember reading an El Reg article about it...
You've not seen the expression "Adventures in nomenclaturism"? It was all the rage a few years ago
Nomenclaturism is referring to the nomenclaturism mindset, not the specific word ("fire" in this case).
Beside, you can't nitpick, and then omit an uppercase and a period.
:-)
Pretty much any time you have lots of energy (60% of TNT for same mass, according to somewhere) and it's readily accessible, it's got to be somewhat dangerous. Consider a centrifugal energy storage system: You have a flywheel, and a motor/generator that spins it up and does regenerative braking to extract the power later. So what happens when it's safely and non-chemically charged, but there was a small defect in one of the necessarily high-precision-machined bearings which subsequently ate itself? It goes titsup really really fast, and then titsleft, and then titswherever, and then titsOhMyGod, and then titsComingRightForUs, and so on. Not a fire hazard and still not absolutely safe.
They are perfecting the battery. It happens to take the form of "adding bits" as you say.
Most likely to be found in the aircraft "Safety Equipment".
Old LiSO2 primary cells, not meeting the latest TSOs. Often found in ELTs, Acoustic Beacons, older avionics. Even on not very old aircraft.
The newer lithium primary cells are good. LiMnO2, TSO-142a if I recall correctly. Safer than a very safe thing.
