Invited for this month's cover picture is the group of Prof. Ping He. The cover picture shows the reaction mechanism of redox mediators in Li‐O 2 batteries. The boat represents the redox mediators (such as I 3− ), serving as the electron carrier between cathodes and Li 2 O 2 products (where the woman stands). The redox mediators offer a promising avenue for reducing the overpotential, promoting the generation of Li 2 O 2 during discharge or decomposition during charge, and improving the rate capability.
