Alkali metal oxygen batteries (AMOBs) have attracted tremendous attention since mid-1990s due to their extremely high theoretical capacity as well as the free and abundant oxygen from air. However, issues such as high overpotential, electrolyte instability and cathode degradation have been hindering its advancing towards practical use. Moreover, the kinetic sluggishness is foreseen to be the critical bottleneck when it comes to applications such as electric vehicles. Meanwhile, solid oxide fuel cells (SOFCs) show a similar electrochemical configuration while demonstrating orders of magnitude higher power capability than that of AMOBs. Herein, we propose to construct a new series of AMOBs that are aiming to achieve AMOBs with a greatly enhanced reaction kinetics. Accomplishment of this project would remarkably promote the industrialization of AMOBs for versatile applications.
