To seek after a high-performance, safety and applicable lithium-air battery, a lot of scholars have conducted numerous research works on cathode materials, catalysts, electrolyte, and lithium cathode. Air electrode optimization and electrolyte stability are the keys to obtaining high performance lithium-air batteries. We review some of the latest research progress on air electrode reaction mechanisms, influence factors of air electrode, materials for air cathode and catalysts in organic electrolyte lithium-air batteries. Meanwhile, advantages and disadvantages of all kinds of porous materials and catalysts, as well as impact on the electrochemical performance of batteries, were analysed. Based on these studies, we put forward the future direction for air electrodes of lithium-air batteries is to build a unique porous electrode structure with new composite oxide catalysts, to achieve high-capacity, long-life lithium-air batteries.
