What do Viagra, popsicles, Corn Flakes, Ivory soap, the kitchen microwave, and champagne have in common? They were all discovered by accident. Add ultra-long-lasting nanowire batteries to that list, thanks to a team of researchers at the University of California Irvine. The average laptop battery is rated anywhere from 300 to 500 charge cycles – completely full to completely empty to completely full again – longer if you don’t use it all up before recharging. The UCI nanobattery endured 200,000 charge cycles over three months “with 94–96% average Coulombic efficiency.” It was effectively still brand new at the end of the experiment.

Let’s go conservative and say the average laptop battery lasts for 1,000 charge cycles, its capacity noticeably diminished after about two years. If that laptop had UCI's nanobattery it would easily last for 400 years (if 1,000 cycles = two years, 200,000 cycles = 400 years). That’s long enough for that laptop to share a name with, but be far less useful than, an actual brick. If UCI can apply its findings to commercial uses, there’s a revolution coming throughout the electronic landscape.
