The use of a higher specific energy material would be advantageous for the solid oxide metal-air battery systems. However, the lighter elements such as sodium, magnesium, lithium and aluminum are much more reducing than the materials studied thus far in the literature. This makes the use of oxide ion conductors such as yttria stabilized zirconia (YSZ) very challenging because they are not chemically (thermodynamically) stable to these higher specific energy materials. This work seeks to address some of the challenges with high temperature lithium-air batteries, by employing additional materials to help suppress the reductive nature of lithium metal.
