Breakthrough Battery Tech for Efficient Water Desalination

For the first time, researchers have designed an electrochemical cell that can desalinate seawater. They think that its cost and efficiency eventually could improve on standard techniques of purifying seawater.
Worldwide demand for freshwater is skyrocketing as the population increases. Many of today’s desalination plants use reverse osmosis or evaporation, both of which require enormous amounts of energy to supply heaters or high-pressure pumps. To find cheaper, room-temperature, energy-efficient solutions, many researchers are looking to nanomaterials and electrochemistry.
