Research Progress on the Catalyst of Oxygen Reduction Electrode for Metal-Air Battery

The electrocatalysts of oxygen reduction reaction(ORR)are the key electrode materials for the metal-air batteries. In this paper, the progress and state-of-art of the research on electrocatalysts of oxygen reduction reaction for metal-air batteries are discussed in detail, including noble metal and alloy, transition metal oxide, and transition metal maro-cyclic compound catalysts. Due to cheap and well performance, the transition metal oxides are considered to be the excellent catalyst with wide application prospect. Through comparison and analysis on various catalysts for the oxygen reduction reaction, it is concluded that finding the catalyst with low cost and high performance is the key factor for development of metal-air batteries.
