Researchers Solve Lithium-Air Batteries' Longevity Problem

Batteries that generate and pass electrons through chemical reactions involving a pure lithium metal conductor and ambient air have a big drawback in the form of a life cycle that typically only lasts a month or so, but researchers with Argonne National Lab, with some help from some figures in the world of academia, have figured out how to stop many of the side reactions that occur during the main energy-producing reaction, making the batteries last far longer. In testing, the batteries held up to hundreds of full charge and discharge cycles. Given that they can hold about five times more energy than comparably sized lithium-ion cells, this could mean smartphone, tablet, and laptop batteries that last five times longer on a charge than current tech, and can maintain capacity and battery health for years, among other benefits.
