Non-precious catalysts for oxygen reduction reactions in the air electrode play a vital role in reducing polarization during cycling and therefore enhancing the performance of metal-air batteries which, among electrochemical energy-storage devices, have the potential to offer the highest energy density, representing the most promising systems for portable (electronics), mobile (electrical vehicles), and stationary (micro-grids) applications. Recent advancements in non-precious catalysts for Li-air and Zn-air batteries are highlighted on page 816 by M. Liu, J. Cho, and co-workers.
