A new method to prevent degradation of lithium–oxygen batteries: reduction of superoxide by viologen

Author affiliations

Abstract

Lithium–oxygen battery development is hampered by degradation reactions initiated by superoxide, which is formed in the pathway of oxygen reduction to peroxide. This work demonstrates that the superoxide lifetime is drastically decreased upon addition of ethyl viologen, which catalyses the reduction of superoxide to peroxide.
