Abstract
Toward global sustainable development, lithium–carbon dioxide (Li–CO 2 ) batteries not only serve as an energy‐storage technology but also represent a CO 2 capture system. Since the beginning of their research in this decade, Li–CO 2 batteries have attracted growing attention. However, Li–CO 2 batteries are still in their infancy and are facing many scientific and technological challenges. From a fundamental perspective, the reaction mechanism of CO 2 cathode is not yet clear enough. Technologically, the high overpotential, low power density, poor rate capability, and limited cycle life impede the development of Li–CO 2 batteries for practical applications. Herein, the recent research progress in Li–CO 2 batteries in terms of reaction mechanisms, cathode catalyst design, electrolyte management, and anode protection are first summarized. In light of the state‐of‐the‐art research advances, future perspectives and research directions are then put forward, aiming to provide insightful information for the development of practical Li–CO 2 batteries.
