Decreasing Anode Corrosion in Metal-Air Batteries

Metal-air batteries can be used in a variety of applications ranging from range extenders for electric vehicles to emergency power systems. Metal-sea-water batteries are primarily used for underwater applications ranging from torpedoes to underwater unmanned vehicles. A team of researchers at the Department of Mechanical Engineering, MIT, has developed an oil displacement system to mitigate open-circuit corrosion in metal-air and metal-seawater batteries.
