High-performance lithium battery anodes using silicon nanowires
This beats the heck out of those ultracapacitors that somehow never seem to make it into the marketplace.

Damn. Sign me up.
I use a surveying instrument that takes a while to set up accurately and can only get 2 to 4 hours on a set of AA’s. I can get better results if I can maintain a single setup for a bigger dataset, but having the batteries die requires repeating the setup and breaks the dataset. This would fix everyting.
Napier, are you using regular alkaline AA batteries?
The reason I ask is because you might benefit from using Lithium batteries or rechargeable Nickel-MH batteries, which have a much higher energy density. It’s the same way with digital cameras and other high-drain devices, in which conventional AA batteries last only an hour or so.
I heard an interview with the inventor on BBC’s Digital Planet, and you might want to dial back the excitement a bit. He wasn’t really clear about the performance, but from the way it sounded, they needed to do some more work on it before it reached it’s described value. He said they had yet to figure out a way to do the cathodes. Also, there’s not been any stress testing on the batteries and I’m sure I don’t have to remind everyone about the ol’ exploding laptop batteries. The inventor was saying it would be at least 3 - 5 years before they hit the market.
(A bit OT. Sry) Rechargables are pretty good; lithiums are very pricy though. My older digicam doesn’t like anything but super-charged NiMH, and even with those took only a few dozen photos. On a long trip I discovered Nickle metal oxide batteries (similar to these, if not those exact ones) that let it take about a hundred photos.
