In-situ regulation of zinc metal surface for Dendrite-Free Zinc-ion hybrid supercapacitors
Journal of Colloid and Interface Science, 2022Aqueous 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, 2021AbstractAqueous 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 NanoManipulating 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
SmallAbstractThe 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).

Overpotential engineering enables dendrite-free zinc anode for high-performance zinc-ion batteries
Journal of Colloid and Interface ScienceLarge-scale energy storage applications can greatly benefit from the low-cost and safe zinc metal anode. However, corrosion, side reactions and dendrite growth in water significantly inhibit the cycle life of zinc-ion batteries. Here, 2-ethyl-1H-benzimidazole (EHB), a strong zincophilic and hydrophobic structure, is introduced into the ZnSO4 (ZS ...

Advanced PEI/PAN Membrane to Suppress Zinc Dendrite Growth in Zinc Metal Batteries
Chemistry – An Asian JournalAbstractAqueous zinc‐ion batteries (AZIBs) are a potential new technology in energy storage due to their high energy density, affordability, and environmental friendliness. The development of AZIBs is still hampered by unchecked zinc dendrite formation during cycling, which results in an unstable interface, a short cycling life, and a considerable ...

Nano Letters
Zinc metal is an attractive anode material of aqueous batteries, but its practical use is persistently hampered by irregular zinc electrodeposition/dissolution and parasitic side reactions. Here we report engineering copper-zinc alloy with a composition- and structure-gradient nanoporous architecture as an effective strategy to regulate high-efficiency
