The critical overpotential for zinc dendrite formation

Journal of Applied Electrochemistry, 1979
The critical overpotential for zinc dendrite growth is determined as 173 mV by the method described by Popovet al. [1]. It was shown that this procedure can be applied successfully to metal deposition processes when there is a large codeposition of hydrogen.

Zinc electrode with reduced dendritic propagation

Journal of Power Sources, 2007
Microporous separators conventionally used in lead-acid accumulators are proposed to substitute rayon-type separator during discharge of zinc anode alkaline accumulators, while the same accumulator is charged mainly through rayon-type separator. Thus the positive qualities of rayon-type and microporous-type separators are amalgamated.

Dendrite growth directions in aluminum-zinc alloys

Metallurgical and Materials Transactions A, 2006
The dendrite growth directions in fcc aluminum-zinc alloys have been measured by electron backscattered diffraction (EBSD) as a function of the zinc concentration,c o . In specimens produced by directional or Bridgman solidification, 〈100〉 dendrites were observed up to 25 wt pct Zn, whereas ...

Manipulating Crystallographic Orientation of Zinc Deposition for Dendrite‐free Zinc Ion Batteries

Advanced Energy Materials, 2021
AbstractThe dendrite issues associated with zinc anode lead to safety hazards and sluggish reaction kinetics, and largely restrain widespread application of aqueous zinc ion batteries (ZIBs). Herein, a functional separator composed of cellulose nanofibers and graphene oxide (CG) is developed for dendrite‐free and exceptionally stable ZIBs, realized by ...

In-situ regulation of zinc metal surface for Dendrite-Free Zinc-ion hybrid supercapacitors

Journal of Colloid and Interface Science, 2022
Aqueous Zn-ion hybrid supercapacitors (ZHSCs) combine the high power density of supercapacitors with the high energy density of batteries. However, the growth of dendrite and spontaneous Zn corrosion damage the service life of ZHSCs and further seriously restrict their large-scale application in energy storage fields.

Revealing the Two‐Dimensional Surface Diffusion Mechanism for Zinc Dendrite Formation on Zinc Anode

Small, 2021
AbstractAqueous zinc‐ion battery is regarded as one of the promising devices for large‐scale energy storage systems owing to its high safety, cost‐effectiveness, and competitive electrochemical properties. However, the dendrite growth on zinc metal anodes dramatically hinders its further practical applications, and the internal mechanism of dendrite ...

Tuning Vertical Electrodeposition for Dendrites-Free Zinc-Ion Batteries

ACS Nano
Manipulating the crystallographic orientation of zinc deposition is recognized as an effective approach to address zinc dendrites and side reactions for aqueous zinc-ion batteries (ZIBs). We introduce 2-methylimidazole (Mlz) additive in zinc sulfate (ZSO) electrolyte to achieve vertical electrodeposition with preferential orientation of the (100) and ...

Zinc‐Seeded PEDOT:PSS Aerogel Host as Highly Reversible Dendrite‐Free Zinc Metal Anode

Small
AbstractThe parasitic reactions and rampant dendrite growth on the Zn anode side pose significant obstacles to the future applications of aqueous zinc ion batteries. Herein, a lightweight anode host is reported by introducing nanosized metallic Zn into the poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) (P‐S) aerogel (Zn/P‐S).
