“…To investigate the effects of K on the stability of the Zn anode, several soluble small molecules with different K values were used, such as zinc acetate (Ac-Zn; log K Ac = 1.50), zinc oxalate (Ox-Zn; log K Ox = 8.15), zinc glycinate (Gly-Zn; log K Gly = 9.96), zinc nitrilotriacetate (NTA-Zn; log K NTA = 11.98), and zinc edetate (EDTA-Zn; log K EDTA = 16.50). [39,40] Here, due to the large values of K, we use log K to present the data. For the convenience of comparison, all the data with five ligands are shown together in Figures S1 and S2 (Supporting Information).…”

Changing the solvation sheath of hydrated Zn ions is an effective strategy to stabilize Zn anodes to obtain a practical aqueous Zn‐ion battery. However, key points related to the rational design remain unclear including how the properties of the solvent molecules intrinsically regulate the solvated structure of the Zn ions. This study proposes the use of a stability constant (K), namely, the equilibrium constant of the complexation reaction, as a universal standard to make an accurate selection of ligands in the electrolyte to improve the anode stability. It is found that K greatly impacts the corrosion current density and nucleation overpotential. Following this, ethylene diamine tetraacetic acid with a superhigh K effectively suppresses Zn corrosion and induces uniform Zn‐ion deposition. As a result, the anode has an excellent stability of over 3000 h. This work presents a general principle to stabilize anodes by regulating the solvation chemistry, guiding the development of novel electrolytes for sustainable aqueous batteries.
