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.'"
