Advanced Energy Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 26, 2025

Abstract Uncontrolled dendrite growth, hydrogen evolution and corrosion challenges associated with zinc (Zn) anodes significantly restrict the practical application of batteries. Herein, a liquid metal gallium (Ga) interface is in situ formed on carbon paper (CP) by electrochemical co‐deposition to construct dendrite‐free Zn‐Ga@CP composite electrode which can regulate transport chemistry Zn deposition at electrode/electrolyte interface. Notably, concurrent reduction 2+ Ga 3+ results formation self‐supporting 3D interpenetrating structure Ga. Compared foil electrodes, highly conductive layer lowers nucleation energy barrier promotes homogeneity electric field ion flux, induces uniform Zn. In addition, low chemical activity prevents high rate reaction parasitic reactions. As result, symmetric cell delivers stable cycling >350 h discharge depth 23.3% ultra‐low voltage hysteresis. Moreover, coin‐type pouch‐type full cells exhibit excellent durability good mechanical stability. This work provides novel regulation strategy for achieving high‐performance anode

Polydentate Ligand Stabilizes Electrolyte and Interface Layer for Anti‐Corrosion and Selective‐Deposited Zn Metal Aqueous Batteries

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Фев. 18, 2025

Abstract Zinc anode suffers from tough issues such as dendrite, corrosion, and hydrogen evolution, which lead to premature battery failure thus restrict the practical application of aqueous zinc‐metal batteries (ZMABs). Herein, a polydentate‐ligand tactic is introduced reconstruct solvation structure, improve corrosion resistance, trigger selective dendrite‐free deposition via β‐Alanyl‐L‐histidine (AH). With abundant amino, amide, carboxyl, imidazolyl groups, AH shows chelation effect, partially substitutes solvated SO 4 2− enters Zn 2+ sheath facilitate desolvation. Those groups also increase strong H‐bond proportion electrolyte, stabilizing water suppressing evolution reactions. Moreover, with multisite coordination, preferentially adsorbs on Zn(002) induce stable functional C, N, O, S‐rich solid‐electrolyte interphase zincophilic hydrophobic properties. It homogenizes both electric field concentration guides preferential growth along (002), realizing anode. As result, obtained electrolyte exhibits high CE 99.28%, extended stability over 6000 h, long lifespan 1000 cycles for Zn//MnO 2 batteries. This work offers novel design strategy additive toward stabilization anodes ZMABs.
