Dendrite-free Zn anode with dual channel 3D porous frameworks for rechargeable Zn batteries

Energy Storage Materials, 2020
Abstract Rechargeable aqueous Zn-ion batteries are highly promising for grid-scale energy storage due to the high safety and low cost; whereas, they also suffer from the limited reversibility and dendrite growth of metallic Zn electrode during plating/stripping processes.

Reviving Zn Dendrites to Electroactive Zn²⁺ by Ion Sieve Interface

Advanced Materials
AbstractZn0 dendrite formation during repeated plating/stripping processes limits the practical use of Zn‐metal anodes in reliable and affordable energy storage. Traditional methods, including dendrite suppression and dendrite regulation, fail under demanding performance conditions due to Zn2+ diffusion limitations and concentration gradients.

A Heteroanionic Zinc Ion Conductor for Dendrite‐Free Zn Metal Anodes

Advanced Materials, 2023
AbstractAlthough zinc‐based batteries are promising candidates for eco‐friendly and cost‐effective energy storage devices, their performance is severely retarded by dendrite formation. As the simplest zinc compounds, zinc chalcogenides, and halides are individually applied as a Zn protection layer due to high zinc ion conductivity.

Optical properties of ZnS nanosheets, ZnO dendrites, and their lamellar precursor ZnS·(NH2CH2CH2NH2)0.5

Chemical Physics Letters, 2002
Abstract The optical properties of 2D wurtzite ZnS nanosheets, ZnO dendrites, and their lamellar precursor ZnS·(NH2CH2CH2NH2)0.5 were investigated. The lamellar precursor ZnS·(NH2CH2CH2NH2)0.5 with highly confined quantum dots effect was produced by a mild solvothermal reaction using Zn(CH3COO)2·2H2O or ZnCl2 with thiourea or sulfur in ...

Tetra-alkyl ammonium hydroxides as inhibitors of Zn dendrite in Zn-based secondary batteries

Electrochimica Acta, 2007
Abstract Several tetra-alkyl ammonium hydroxides have been proposed and testified as novel inhibitors of Zn dendrite to replace the well-known tetra-alkyl ammonium bromides. In order to assess the efficacy of these hydroxides, current–time technique using potentiostatic electrodeposition, conductivity measurement, cycling test and scanning electron ...

Zn(002)-preferred and pH-buffering triethanolamine as electrolyte additive for dendrite-free Zn anodes

Chemical Communications
TEOA as an electrolyte additive preferentially adsorbs on Zn(002) and enhances Zn(002) exposure, suppressing dendrite growth and side reactions. Meanwhile, it diminishes the change in pH near Zn anode, reducing the formation of byproducts.
