This study reports the use of ammonium fluoride as an additive in zinc sulfate electrolyte to enhance zinc anodes. The formation of electrostatic shielding layer and ZnF2-rich solid-state interphase layer can effectively inhibit side reactions and dendrite growth, leading to improved performance in zinc cells.
Herein, ammonium fluoride is reported as an additive within 1 M ZnSO4 aqueous electrolyte to improve zinc anodes. The as-formed electrostatic shielding layer and ZnF2-rich solid-state interphase layer can jointly inhibit side reactions and dendrite growth. Consequently, symmetric Zn||Zn cells, asymmetric Zn||Cu cells and Zn||MnO2 cells with the additives present dramatically enhanced performance in comparison to the ones with pure ZnSO4 electrolyte counterparts. This work proposes a facile but effective method to achieve highly reversible zinc anodes. NH4F is reported as an effective electrolyte additive to realize high-performance zinc electrodeposition in aqueous electrolytes.
