Engineers have found a way to eliminate the fluid flow 'dead zones' that plague the types of electrodes used for battery-based seawater desalination. The new technique uses a physics-based tapered flow channel design within electrodes that moves fluids quickly and efficiently, potentially requiring less energy than reverse osmosis techniques currently require.

A battery that needs feeding instead of charging? This is exactly what researchers have achieved with their 3D-printed, biodegradable fungal battery. The living battery could supply power to sensors for agriculture or research in remote regions. Once the work is done, it digests itself from the inside.

Most solids expand as temperatures increase and shrink as they cool. Some materials do the opposite, expanding in the cold. Lithium titanium phosphate is one such substance and could provide a solution to the problem of steeply declining performance of lithium-ion batteries in cold environments. Scientists have now demonstrated its suitability for use in electrodes for rechargeable batteries.
