The Lady and the li-ion
IEEE Spectrum ^ | 03-2008 | Tekla S. Perry

Posted on 03/21/2008 5:42:35 AM PDT by grey_whiskers

YOUR WORLD increasingly runs on lithium-ion batteries. Chances are good that your phone, laptop, camera, portable music and video players, radios, and game consoles keep going only as long as there are lithium ions churning around inside them. Lithium-ion batteries are getting into your power tools. Soon they’ll even be in your car.

So it’s a shame that after nearly four decades of intensive development, lithium-ion batteries still leave plenty to be desired. They fade fast—although their energy capacity starts out higher than that of any other kind of mass-market battery, it can drop more than 25 ­percent per year in typical applications. And then there are the persistent reports of flameouts: just this January, ­journalists gathered at a Korean hospital witnessed a colleague’s laptop burst into flames. Remember the iPod that burned up in a man’s back pocket, or the Dell laptop that went up in flames at a conference in Japan? Their former owners sure do.

Nice to see IEEE articles here. You know they won’t be written by idiot reporters who don’t understand the science.

That was a great read for a brain dead 75 year old horse and buggy guy. Related to this story...a week ago
Thursday I purchased a new holster for my 3225 Kyrocera cell phone. It is a drop in open top design and a little snug on the phone. I had to charge that puppy every night because the battery was DEAD. On the 4th afternoon I took it out of the holster and it was HOT to the touch.

I thought the phone had gone bad so I left it out of the holster on the counter and it still had a charge the next morning. I put it back in the old ventilated holster on Tuesday and it is still holding a charge and works normally...

Thanks for *PING*ing me to something I had just posted.

(Glad to see I'm not the only one who's done that.)

Cheers!

Oops, I was in a rush, that was supposed to read “thanks grey whiskers”. [blush]

But hey, have you seen this one?
