The front cover represents the reaction mechanism of redox mediators in Li‐O2 batteries. The boat denotes the redox mediators (such as I3−), serving as the electron carrier between cathodes and Li2O2products (where the woman stands). The redox mediators offer a promising avenue for reducing the overpotential, promoting the generation of Li2O2 during discharge or decomposition during charge, and improving the rate capability. More information can be found in the Review by W. Zhao et al.
