Lithium–oxygen batteries are innovative devices that generate power from atmospheric oxygen trapped inside porous, carbon-based electrodes. These batteries are significantly lighter than traditional lithium-ion batteries, and thus have the potential to extend the driving range of electric and hybrid vehicles. However, many practical challenges remain for lithium–oxygen batteries, most notable of which is the buildup of insoluble lithium peroxide by-products in the carbon electrode, which can cause the battery to cease operation after only a few charge cycles.
