摘要

锌阳极的腐蚀、枝晶生长和析氢阻碍了水锌电池的广泛应用。本研究引入亲锌疏水分子2-氨基-6-三氟甲氧基苯并噻唑（TBA），通过“位阻效应”修饰Zn||ZnSO4电解质界面，形成保护层，缓蚀效率达到99.1 %。因此，Zn||Zn电池在5 mA cm−2下稳定循环超过1600 h， Zn||Cu电池在1 mA cm−2下稳定循环超过300次，库仑效率（CE）为99.25% %。Zn||α-MnO2满电池也表现出良好的稳定性。本研究为制备稳定的水性金属电池提供了一种新方法。

New strategy for zinc anode corrosion protection: Development of a benzothiazole-based inhibitor and its optimization for battery performance

The widespread application of aqueous zinc-ion batteries is hindered by corrosion, dendritic growth, and hydrogen evolution on zinc anodes. This study introduces the zincophilic and hydrophobic molecule 2-amino-6-trifluoromethoxybenzothiazole (TBA) to modify the Zn||ZnSO₄ electrolyte interface through “steric effect”, forming a protective layer with a corrosion inhibition efficiency reaching 99.1 %. Hence, Zn||Zn cells cycle stably for over 1600 h at 5 mA cm⁻², and Zn||Cu cells for over 300 cycles at 1 mA cm⁻² with 99.25 % coulombic efficiency (CE). Zn||α-MnO₂ full cells also show good stability. This research offers a novel method for stable aqueous metal batteries.
