Rhubarb battery could finally free solar households from the electricity grid

Harvard scientists have developed a metal-free flow battery based on the electrochemistry of the naturally abundant, inexpensive, organic molecules that store energy in plants and animals. The new battery could provide the final piece in the renewable energy puzzle – storing energy from sources such as wind and solar economically and reliably. Flow batteries work […]

Cheap and simple desalination unit runs from battery

Using a small electrical field that removes the salts from seawater, German and American scientists have invented a new method for the desalination of seawater that consumes much less energy and is dramatically simpler than conventional desalination techniques. The new technique, known as electrochemically mediated seawater desalination, is described in the journal Angewandte Chemie. To […]

Stretchy battery can bend and twist

A team of scientists from Northwestern University and the University of Illinois are the first to demonstrate a stretchable lithium-ion battery – a flexible, wirelessly charged device that could power a range of innovative, stretchable electronic appliances. Northwestern’s Yonggang Huang and the University of Illinois’ John A. Rogers detail their invention in the journal Nature […]
