Distinguished as safe, powerful and flexible but plagued by a short life, sulphur-based redox flow batteries have been given a boost to their duration by CUHK engineers, ending a long unsolved challenge. They have designed a novel membrane, keeping the battery’s two electrodes apart and reducing the loss of active materials, so ramping up its lifetime, stability, and its usefulness in grid-scale energy storage devices.
High energy batteries, in cell phones and laptops, can blow up in your face. Research around that problem surfaced with a solution from a surprisingly different field. It is a soluble polymer used in skin cream that can also stabilise battery output. Soon, putting a phone on your cheek will be as gentle on your skin as moisturizer.
