Zusammenfassung:Systems and methods of the various embodiments may provide low cost bifunctional air electrodes. Various embodiments may provide a bifunctional air electrode, including a metal substrate and particles of metal and/or metal oxide catalyst and/or metal nitride catalyst coated on the metal substrate. Various embodiments may provide a bifunctional air electrode, including a first portion configured to engage an oxygen reduction reaction (ORR) in a discharge mode and a second portion configured to engage an oxygen evolution reaction (OER) in a charge mode. Various embodiments may provide a method for making an air electrode including coating a metal substrate with particles of metal and/or metal oxide catalyst and/or metal nitride catalyst. Various embodiments may provide batteries including air electrodes.
