Building Metal‐Molecule Interface towards Stable and Reversible Zn Metal Anodes for Aqueous Rechargeable Zinc Batteries

Abstract: Aqueous zinc ion batteries (AZIBs) are receiving increasing attention for large-scale energy storage systems owing to their appealing features with intrinsic safety, low cost, and scalability. Unfortunately, the water-induced parasitic reactions and dendrite growth on the Zn anode severely impede the further development of AZIBs. Herein, a thiourea additive is introduced into ZnSO 4 electrolyte to construct unique metal-molecule interface for simultaneously regulating the Zn anode interface chemistry and the b… Show more

“…The 2 H chemical shift in D 2 O increased from 4.7015 to 4.7172 ppm with the addition of 2 m ZnSO 4 , suggesting the weaken OH bond with the D 2 O molecule due to the strong coordination between Zn 2+ and D 2 O ( Figure a). [ 15 ] Notably, with pure BC membrane and ZnHAP/BC separator added into the 2 m ZnSO 4 solution, the 2 H chemical shift increase to higher value of 4.7210 and 4.7192 ppm, indicating the formation of H‐bonds between BC and D 2 O, thus resulting in a weak interaction between Zn 2+ ions and water molecules and the restricted water reactivity. The H‐bond formation between the separator and H 2 O was also confirmed by the Raman spectra.…”

“…The adsorption of Ac − anions on the Zn anode could correspondingly reduce the population of OTF − anions in the vicinity of Zn anodes and thus limit the decomposition of OTF − anions. 37 Without the addition of acetate salt, substantial decomposition of OTF − anions could be evidenced by the formation of CF 3 , ZnF 2 , and ZnSO 3 /ZnSO 4 in X-ray photoelectron spectroscopy (XPS) (Figures 3d,e and S17a). However, the functions of decomposition products are highly correlated with the specific decomposition mechanism of OTF − anions in the electrolytes.…”

“…Figure S3 shows the cyclic voltammetry (CV) profiles of the symmetric cells with the ABA@Zn anodes at various reaction times. The cathodic overpotential of CV reflects the nucleation barrier for Zn deposition, 27 and thus, it is used to determine the optimized ABA fabrication time. The Zn deposition overpotentials of different samples are listed in Figure S4.…”
