Video Shows Why Recharging Kills Batteries 111
sciencehabit writes with this except from Science: "You may not give a lot of thought to what happens inside the battery of your laptop or cell phone, but to judge from this video, it's not a dull place. The battery in question is a miniature rechargeable lithium-ion device, and the clip shows what happens when it is charged. As lithium ions flow from the positively charged cathode into the 200-nanometre diameter wires of tin oxide that make up the negatively charged anode, the nanowires writhe and bulge, causing them to expand up to 2.5 fold. The wires also change structure from a neatly ordered crystal to a disordered glassy material. These distortions may explain why such batteries ultimately wear down. Knowing more about the process may help researchers develop longer lasting, and perhaps much smaller, batteries in the future."
You got all that from THAT video? (Score:5, Funny)
I keep watching it over and over again, in its 17 second glory... and I honestly wish I could believe you.
No, I'm almost positive (no pun intended) that this is actually a Rorschach inkblot VIDEO. You see whatever your subconscious is thinking about. Edwin Cartlidge is obviously suffering from the stress of a bad phone lithium ion battery - and when he stumbled across this video thats what he percieved is happening.
For me, I think this is the opening bit to a Frank Miller or James Bond Flick - I can almost hear the rock/Jazz music chime in.
What about you guys? What do YOU see?

It says you've seen too much of David Lynch's films, which is to say, more than 10 minutes.
