Constructing Artificial Zincophilic Interphases Based on Indium–Organic Frameworks as Zinc Dendrite Constraint for Rechargeable Zinc–Air Battery

Small, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 26, 2025

Abstract The practical application of zinc (Zn)–air batteries is largely restricted by their inferior cyclability, especially under fast‐charging conditions. Uneven Zn plating and dendrite formation result in short circuits. In this work, an artificial solid‐electrolyte interphase (SEI) constructed using indium–organic frameworks (IOF) on the anode. It contains a hybrid architecture that integrates chemical morphological contributions to regulate behaviors constrain growth. atomically dispersed 3+ provides zincophilic sites tune nucleation kinetics promote preferential growth along (002) crystal facet. Meanwhile, IOF exhibits nanosheets‐assembled microspheres with well‐ordered porous architecture, which promotes mass transfer affords space for electrodeposition. influence SEI microstructure plating/stripping behavior further investigated validated post‐cycling characterizations. With based SEI, symmetric cells perform stable cycling over 1750 h at 10 mA cm −2 . When powering Zn–air batteries, life extended 800 h, approximately four times longer than pristine foil.

Promoting Migration Kinetic of Desolvated Zn²⁺ by Functional Interlayer Toward Superior Zn Metal Anode

Small, Journal Year: 2025, Volume and Issue: unknown

Published: March 21, 2025

The development of Zn metal anodes is challenged by non-uniformity ion flux causing inhomogeneous deposition and strong solvation Zn(H2O)6 2+ resulting in adverse side reactions. Applying intermediate protecting layers with high affinity to Zn2+ a popular effective solution, but it also limits the migration. A functional MXene-based interlayer designed this work modify glass fiber separator achieving balanced adsorption energy By coating porous silica on MXene surface, instinct advanatges are mostly reserved while optimized. Such an enables uniformity desolvated Zn2+, contributing rapid kinetic for excellent rate performance inhibited reactions long-term cycling stability. As result, functionalized anode delivers steady plating/stripping cycles more than 5000 h at 0.1 mA cm-2 700 5.0 cm-2. Zn||MnO2 full cells exhibit superior capabilities (173 mAh g-1 2.0 g-1) cycle (254.7 after 1000 0.5 g-1). This provides feasible strategy preparing interlayers toward or other anodes.

Engineering Interfacial Fast Ion Channels toward Highly Stable Zn Metal Batteries

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(5), P. 6623 - 6631

Published: Jan. 23, 2024

The development of aqueous zinc-ion batteries (AZIBs) is hindered by dendrites and side reactions, such as interfacial byproducts, corrosion, hydrogen evolution. construction an artificial interface protective layer on the surface zinc anode has been extensively researched due to its strong operability potential for large-scale application. In this study, we have designed organic hydrophobic hybrid inorganic intercalation composite coating achieve stable Zn2+ plating/stripping. poly(vinylidene fluoride) (PVDF) effectively prevents direct contact between free water anode, thereby mitigating risk dendrite formation. Simultaneously, vanadium phosphate (VOPO4·2H2O) after insertion polyaniline (PA) establishes a robust ion channel facilitating rapid transport Zn2+, thus promoting uniform electric field distribution reducing concentration polarization. As result, performance modified PVDF/PA-VOP@Zn exhibited significant enhancement compared with that bare anode. assembled symmetric cell exhibits exceptionally prolonged lifespan 3070 h at current density 1 mA cm-2, while full battery employing KVO cathode demonstrates remarkable capability undergo 2000 cycles 5 A g-1 capacity retention rate 78.2%. This study offers valuable insights into anodic modification strategy AZIBs.
