Synergistic Gradient Design of a Sandwich‐Structured Heterogeneous Anode for Improved Stability in Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 8, 2025

Abstract Aqueous Zn‐ion batteries provide a low‐cost energy storage solution but face challenges such as dendrite formation and interface instability, which become more pronounced at high currents capacities. Herein, scalable sandwich‐structured heterogeneous anode is proposed for aqueous zinc that integrate three functionally synergistic layers. A robust 3D ZnO@C substrate (from calcined Bio‐MOF‐100, BMC) with dense nucleation sites guides orderly Zn deposition, while controllable pre‐deposited intermediate layer precisely regulates 2 ⁺ flux. An artificial indium‐based protective top‐layer chemically isolates the active from electrolyte, effectively suppresses interfacial corrosion, enhances interlayer contact to minimize impedance maintaining structural integrity during cycling. The synergies endow symmetric cell an ultra‐long cycle life exceeding 2000 h stable plating/stripping remarkable depth of discharge (76%) under current/areal capacity conditions (6 mA cm −2 /12 mAh ). Additionally, BMC@Zn@In//(NH 4 ) V 10 O 25 ·8H full battery achieves lifespan 5000 cycles, BMC@Zn@In//activated carbon hybrid supercapacitor demonstrates impressive 16 000 cycles. This study identifies mechanism ultra‐stable promising applications in batteries.

Rational Design of a Bilayer Interface for Long‐Term Stability of Zn Anodes and MnO₂ Cathodes

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 28, 2025

Abstract Understanding the composition–characteristics–performance relationship of electrolyte–electric double layer–electrode–electrolyte interface (EEI) is crucial to construct stable EEIs for high‐performance aqueous Zn–MnO 2 batteries (AZMBs). However, interaction mechanisms in AZMBs remain unclear. This work introduces sodium thioctate (ST) into ZnSO 4 electrolyte a bilayer EEI on both Zn and MnO electrodes. First, zincophilic ST regulates solvation structure hydrated 2+ , suppressing corrosion hydrogen evolution reaction. Second, specific adsorption reconstructs inner Helmholtz plane, facilitating desolvation homogenizing charge distribution. Finally, molecules undergo reversible polymerization at interface, forming with poly(zinc thioctate) outer layer ZnS–organic amorphous layer, which ensures uniform zinc‐ion flux enhances mechanical stability. Additionally, dynamic disulfide bonds further enable self‐regulation self‐healing mitigating damage during cycling. As result, ST‐enhanced symmetric battery achieves 7800 cycles 60 mA cm −2 while AZMB exhibits only 0.0014% capacity decay over 10 000 2000 g −1 . engineering strategy offers effective guidance rational design safe long‐life batteries.
