Microbatteries Built on a Bed of Nails

nadamsieee writes "The good folks at IEEE Spectrum have a news brief about a newly invented method of creating microbatteries using an electrode that looks like a bed of nails. The method was created by a team led by Prof. Marc Madou of UC Irvine. IEEE Spectrum notes that 'according to the researchers, a battery using such an electrode can generate 78 percent more power than a stacked-plate microbattery of the same volume.'"

Re:This is the same tech in all modern batteries.

Nothing to see here, Move along.

Nothing to see here? We understand the science behind the idea, but until now no one has made this tech. (at least not in this way)... Whats with the current trend of /.ers that are spewing randomly that every piece of news here sucks? maybe its just the people here that are so critical of the news that suck? why dont you submit some better news if this isnt good enough?

Interesting, but

I'd sell a body part to be able to get a "battery" that was somwhere between a capacitor and battery in features. Supercapacitors are getting closer, but even 10F is no where near a small battery in capacity.

I'm working on a hybrid vehicle, and finding a way to make good use of the regenerative braking power is a real challenge. Lead acids can only take a charge so fast, usually less than 0.1 of the power available during braking, unless you completely oversize the battery banks.

I want something with a very low charge impedance that can basically lock the shaft of the motor/generator, if need be.. completely eliminating friction brakes.

This would have bigger applications... Imagine charging your laptop in 10 minutes, then running for 6 hours.

So these advances in power density and discharge impedance are good, but tangential to what I think will be the real killer app, a super low charging impedance battery.
