Abstract

In recent years, the concept of a rechargeable aqueous Zn-CO₂ battery has attracted extensive attention, including a dual functionality of supplying power and simultaneously converting CO₂ into value-added chemicals or fuels. The state-of-the-art research has been mainly focused on the exploration of working mechanism and catalytic cathodes, but hardly applies an integrative view. Although a large number of studies has proven the feasibility of rechargeable aqueous Zn-CO₂ battery, challenges remain including the low CO₂ conversion efficiency, poor battery capacity, and low energy efficiency. This review systematically summarizes the working principles and devices, and the catalytic cathodes used for Zn-CO₂ battery. The challenges and prospects in this field are also elaborated, with the hope of providing insightful guidance for future development of a rechargeable aqueous Zn-CO₂ battery with high performanc
