New Electrolyte Enables a Stable Power Supply to Win the “Cold War”

Life in an extremely cold region without electricity for heating and lighting can be a miserable experience, especially as existing battery technologies cannot retain a reliable power supply in such cold weather. When winter storms sweep across cities, the power crisis they cause can leave millions of people without electricity. CUHK researchers are trying to fix that with a new technology that promises to bring stability to electrical storage, even at very low temperatures.

New Membrane Gives Duration Boost to Redox Flow Battery

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.

New “Soft Power”: Batteries Safe and Stable as Skin Cream

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.
