Dual redox catalysts for oxygen reduction and evolution reactions: towards a redox flow Li–O2 battery

Abstract

A redox flow lithium–oxygen battery (RFLOB) by using soluble redox catalysts with good performance was demonstrated for large-scale energy storage. The new device enables the reversible formation and decomposition of Li₂O₂via redox targeting reactions in a gas diffusion tank, spatially separated from the electrode, which obviates the passivation and pore clogging of the cathode.
