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 ...

Reviving Zn Dendrites to Electroactive Zn ²⁺ by Ion Sieve Interface

Advanced Materials
Abstract Zn 0 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 ...

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 ...

Construction of small Zn-air batteries by dendrite-free Zn electrodeposition using renewable electricity

Materials Plus, 2023
In this work, the possibility to make small, handy but efficient Zn-air batteries has been studied. Battery anode has been constructed by dendrite-free Zn electrodeposition on conductive substrates made of either carbon cloth or brass. Brass was an alloy containing 71% Cu and 21% Zn. Zn electrodeposition has been monitored by applying several (negative)

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.

Dendrite-free Zn anodes enabled by interface engineering for non-alkaline Zn-air and Zn-ion batteries

Energy Materials
Aqueous zinc-metal batteries hold immense promise for large-scale energy storage applications due to their cost-effectiveness and superior safety features. However, uncontrolled dendrite growth, corrosion and side reactions in aqueous environments destabilize the electrode/electrolyte, leading to Zn plating/striping irreversibility. Herein, a low-cost,

Achieving the Dendrite‐Free Zn Anode by Inducing the (101)‐Preferred Electrodeposition of Zn Crystals

Advanced Energy Materials
AbstractPrevious studies have primarily focused on promoting the (002) crystal plane of electrodeposited zinc (Zn) to grow thin Zn plates parallel to the electrode surface and thus achieving the dendrite‐suppressed Zn anodes. In contrast, this work adopts a novel approach. In situ construct a tin (Sn) modification layer on Zn foil.
