The oxygen‐ K pre‐edge has been broadly used to discuss the oxygen redox states in batteries. Here, through combined experimental and in theoretical studies of a number of oxide electrodes, we conclude that the O‐ K pre‐edge evolution predominantly represents the transition metal state variation, which is summarized to benchmark future research.
