Progress of Aqueous Rechargeable Zn–CO 2 Batteries with a Focus on Cathode Bifunctional Catalysts

Year: 2025

Type: article

Abstract: Aqueous rechargeable Zn–CO 2 batteries are emerging as a promising technology for sustainable energy storage and carbon dioxide (CO 2 ) utilization, owing to their high safety, theoretical capacity, and product diversity. Despite their significant theoretical potential, the application of Zn–CO 2 batteries is hindered due to several challenges, including low product‐added value, low current density, poor cycle stability, and excessively high overpotential. These issues hinder the widespread use of Zn–CO 2 batteries. Cathode bifunctional catalysts, which can promote the CO 2 reduction reaction while lowering the reaction energy barrier for the oxygen evolution reaction, have garnered research interest in recent years. However, a systematic summary is rarely reported. This review mainly focuses on the cathode catalysts of aqueous rechargeable Zn–CO 2 batteries, summarizing current research progress in terms of devices, reaction mechanisms, and bifunctional catalysts. This review also discusses existing challenges and prospects, offering enlightenment for the future research of Zn–CO 2 batteries.
