摘要
Rechargeable aqueous zinc-based batteries (AZBs) have received massive attention as promising contenders for the future large-scale energy storage due to their low cost, inherent safety, and abundant resources. However, the insufficient energy density and poor stability have become the key to hinder their further application. As is well known, the energy densities (E, Wh kg-1 ) of AZBs are determined by the specific capacity (mAh g-1 ) and output voltage (V). Given the fixed redox potential and capacity of the Zn metal anode, the energy density of AZBs is mainly determined by the cathode material, and the rich material systems of the cathode provide more possibilities to this field. Meanwhile, the methods to improve the stability and performance of the Zn anodes have gained more and more attention due to the severe Zn dendrite growth that can pierce the separator and lead to short-circuiting of the cell. Therefore, in this review, we comprehensively summarize the rational design methods in optimizing the cathode, anode, and device architecture, and classic examples of each catalogue are discussed in details as well. Last, the issues and outlook for further development of high performance AZBs are also presented.
