Desalination Breakthrough: Engineers Solve “Dead Zone” Problem

A new tapered flow channel design for electrodes improves the efficiency of battery-based seawater desalination, potentially reducing energy use compared to reverse osmosis. This breakthrough may benefit other electrochemical devices, but manufacturing challenges need to be addressed. Engineers have developed a solution to eliminate fluid flow “dead zones” in electrodes used for battery-based seawater desalination. [...]
