Abstract

A catalyst, active layer, and cathode for metal air and other air-assisted cells and methods of producing these are disclosed. The cathode produced comprises a substantially unoxidized carbon support with a manganese or other oxide catalyst. The support maintains its inherent water repellency, conductivity and active sites. The cathode is therefore capable of sustaining significantly high currents for prolonged duration, at higher operating voltages, enabling the extension of metal air technology for higher power devices.
