摘要

1 Introduction Zn-air batteries (ZABs) have attracted massive attention due to their high theoretic energy density,which are considered as a prospective technology to meet the energy requirements for future electric vehicles and utility-scale energy storage system [1-4].However,the cell voltage and energy density in the ZABs reported so far were still far away from satisfactory for the practical application.
