Nanowire Electrode Could Lead to Eternal Batteries

Apr-22-16 Researchers have created a nanowire-based electrode that could lead to batteries with almost limitless recharge cycles.

Although nanowires have been known to be an ideal material for creating improved batteries, they are quite fragile, and cannot survive the battery cycle. To help overcome this obstacle, scientists at the University of California, Irvine, covered the nanowires with a protective coating that drastically increases their lifespan.

The new nanowire-based electrodes are made up of a gold nanowire that has been coated with manganese dioxide. That wire was then encased in an electrolye made up of a Plexiglas-like gel, resulting in a reliable and rugged electrode able to withstand 200,000 recharge cycles with no noticeable degradation.
