Zinc powder-based anodes encounter significant challenges, including severe side-reactions and non-uniform Zn plating-stripping processes. These issues lead to poor reversibility and low zinc utilization, which substantially impede their practical applications. Herein, we fabricated a multifunctional carbonyl-containing zinc metharcylate (ZMA) layer on the surface of three-dimensional (3D) zinc powder anode through in-situ modification. The ZMA layer with high electronegativity and highly nucleophilic carbonyl group assists the de-solvation process, which is conducive to the Zn2+ transport and homogenization of the ionic flux. In addition, the hydrophobic carbon chains in ZMA work as a protective layer to reduce the Zn powder direct contact with free-water and significantly improving side-reactions resistance. Finally, through the synergistic effect of ZMA and 3D Zn structure, the prepared electrode could cycle stably at 20 mA cm−2/20 mAh cm−2 for 1153 h (depth of discharge: 38.10%). The stable 3D Zn-MnO2 battery with a high capacity retention (84.2% over 500 cycles) is also demonstrated.
期刊介绍：
Science China Materials (SCM) is a globally peer-reviewed journal that covers all facets of materials science. It is supervised by the Chinese Academy of Sciences and co-sponsored by the Chinese Academy of Sciences and the National Natural Science Foundation of China. The journal is jointly published monthly in both printed and electronic forms by Science China Press and Springer. The aim of SCM is to encourage communication of high-quality, innovative research results at the cutting-edge interface of materials science with chemistry, physics, biology, and engineering. It focuses on breakthroughs from around the world and aims to become a world-leading academic journal for materials science.
