New Electrode Lets Batteries Charge In 10 Seconds
Al writes "A new lithium-ion electrode allows batteries to be charged and discharged in 10 seconds flat. Developed by Gerbrand Ceder, a professor of materials science at MIT, it could be particularly useful where rapid power bursts are needed, such as for hybrid cars, but also for portable electronic devices. In testing, batteries incorporating the electrodes discharged in just 10 seconds. In comparison, the best high-power lithium-ion batteries today discharge in a minute and a half, and conventional lithium-ion batteries, such as those found in laptops, can take hours to discharge. The new high rate electrode, the researchers calculate, would allow a one-liter battery based on the material to deliver 25,000 watts, or enough power for about 20 vacuum cleaners."
...how many libraries of congress per square inch is that, again?
That sucks.
I read Slashdot for the headlines, because the headlines, unlike the articles, are usually original and never duplicated
> deliver 25,000 watts, or enough power for about 20 vacuum cleaners."
What could possibly go wrong with that!!??
Sig Battery depleted. Reverting to safe mode.
Great, by the time I have backed out of the driveway I'll need to recharge it.
for about 10 sec.
Where does the heat go on rapid discharge?
Or is this the Sony method of rapid discharge?
a page of comments and no one has yet said:
"10 seconds? the average /. geek discharges faster than that"
sigh.
Wow, now we can expect to see spectacular laptop fires hot enough to burn through an engine block. Where can I get some of those batteries? Sony?
My last laptop battery was faster than this after a few years, it would completely discharge in 5 seconds, not a slow 10 seconds!
All you need is a wall socket that can deliver 25,000W!
Note to self: pick up some 100A fuses on the way home.
Repton.
They say that only an experienced wizard can do the tengu shuffle.
I thought of writing I disclaimer saying as much, but my submit button discharged too fast.

You know they have drugs for that. The blue pill and all.

Anyone else notice this from the article?
Wouldn't it be something if someone trademarks this use of lithium diphosphate on targeted crystal faces as, oh, I dunno, dilithium crystals?
First, transparent aluminum, and now this!
Program Intellivision!
I prefer to see how deep the rabbit hole goes!

You should think more along the lines of a Beowulf Cluster of Roombas.
This issue is a bit more complicated than you think.
In the fuse draw of a local college electronics lab I found a length of 6inch nail lovingly cut to length with cleaned ends, painted round the middle with the designation "10000A, slow-blow" (Apparently one of the techs had a dead scope that couldn't be powered up - it just blew the fuse. Hence the nail. Bung it in and now you know where the hard short *was*. It's the melted patch with the smoke coming out...)
Red to red, black to black. Switch it on, but stand well back.
so thats what the kids call it these days
Apparently, the "Bunny Trail" is a symbolic representation of one's latent homosexual desires. It's quite an interesting read!
Is there a moderation for +1 Too Much Informative?
