Review outlines oxygen electrocatalysis advances in metal-air battery systems, highlighting strategies to resolve cathode kinetics and enhance energy density.

Key Points

To examine electrocatalytic mechanisms and evaluate catalyst design strategies across aqueous and nonaqueous metal-air battery systems.
Reviewed electrocatalytic mechanisms for the oxygen reduction reaction and oxygen evolution reaction across aqueous and nonaqueous electrolytes.
Assessed seven distinct catalyst groups: transition metal oxides, functional carbons, metal oxide-nanocarbon hybrids, metal-nitrogen complexes, transition metal nitrides, conductive polymers, and precious metal alloys.
Nonaqueous metal-air configurations such as Li-air deliver theoretical energy densities substantially exceeding conventional lithium-ion batteries.
Cathodic reaction kinetics remain the primary performance bottleneck across both aqueous and nonaqueous systems due to sluggish oxygen reduction and evolution mechanisms.
Electrolyte-dependent mechanistic differences necessitate distinct catalytic materials, with nonaqueous systems facing additional hurdles in stability and reversibility.
