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.
