Mechanism for aprotic sodium-air batteries

The automobile industry has been interested in finding batteries that allow electric cars to travel at a comparable distance to gas-powered cars. Currently, electric cars use a lithium ion battery, but there is interest in a metal battery that uses air as the cathode because the battery would not need to house the cathode solution. Originally, researchers focused on lithium-air batteries because energy density is similar to gasoline. However, several technical barriers have stymied progress with lithium-air batteries.
