With theoretical energy densities as much as 10 times that of current lithium-ion batteries, lithium-air (or lithium-oxygen) batteries hold tremendous potential for storage of renewable energy and use in mobile devices and electric cars. Although a practical lithium-air battery is still some years from becoming a commercial reality, researchers at the University of Cambridge have developed a working laboratory demonstrator that shows how many of the problems holding back the development of lithium-air batteries could be overcome.
