The success of Li–air/O 2 batteries has brought extensive attention to the development of various promising non‐Li metal–O 2 batteries, such as Zn–O 2 , Al–O 2 , Mg–O 2 batteries, etc., which have exhibited unique advantages, such as low production cost, high energy density, and much enhanced safety. The versatile non‐Li metal–O 2 batteries provide a better opportunity for meeting the practical requirements for sustainable energy supplies in various applications. A high‐performance cathode in non‐Li metal–O 2 batteries that can effectively trigger both oxygen reduction and evolution reactions and thus boost the overall battery performance is of great research interest. In this article, a comprehensive review on the development of Li‐free metal–O 2 batteries and particularly focusing on the oxygen catalytic cathodes for both primary and secondary non‐Li metal–O 2 batteries is carefully performed. The current challenges and potential solutions are also outlined and proposed. Through carefully selecting and rationally designing promising catalytic cathodes, a series of non‐Li metal–oxygen batteries toward practical energy storage applications are highly anticipated.
