Abstract

By using ethylenediamine (En) as a complexing agent, the impact of various Zn²⁺ coordinated configurations on Zn anode reversibility was systematically studied. With the predominant configurations of [Zn(En)]²⁺ and [Zn(En)₂]²⁺ in the electrolyte, both symmetric Zn/Zn cells and Zn/NiHCF full cells exhibit significantly improved cycling stability compared to the counterparts with pure ZnSO₄ electrolyte.
