Self-assembled multilayers direct a buffer interphase for long-life aqueous zinc-ion batteries

Abstract

Rechargeable aqueous zinc-ion batteries (AZIBs) have extensive application prospects in stationary energy storage grids, yet they are practically retarded by interfacial instability and dendrite growth. Herein, we design a specifically...

Mimicking ion and water management in poultry breeding for highly reversible zinc ion batteries

“…Successful efforts have been made to optimize the water and Zn 2+ flows by creating conductive nanostructures to unify the interfacial electrical field, 16 employing electrolyte additives to break the solvation structure of Zn 2+ , 17 designing artificial interfaces to insulate water penetration or increase the interfacial Zn 2+ concentration. 18–21 Nevertheless, efficient water and Zn 2+ flows can hardly be achieved simultaneously. For instance, many protective layers have been developed to stabilize the Zn anode, including inorganic compounds like ZnS, 22 CaCO 3 , 23 metal–organic frameworks, 24 and organic polymers such as polyamide, 20 poly(vinyl butyral) 25 and carbon nitride.…”

Trade-off between Zincophilicity and Zincophobicity: Toward Stable Zn-Based Aqueous Batteries

“…Moreover, the zincophobic electrolyte exhibits a stronger affinity for the SEI formed by the horizontal stacking of zinc hydroxide sulfate, which ensures rapid Zn 2+ flux while inhibiting the growth of dendrites. To further enhance the durability and reliability of aqueous Zn chemistry, Li et al designed a zincophilicity and hydrophobicity self-assembled multilayer (SAM) using l -cysteine as a molecular building block . This SAM is capable of reconfiguring in response to environmental conditions and triggering a dynamic replenishment interphase to confront the change in electrode morphology.…”

Inhibition of Zinc Dendrite Growth by WC-Cellulose Separators for High-Performance Zinc-Ion Batteries

“…1−4 Thus, AZIBs have been considered as one of the most promising candidates for highdensity energy-storage systems in the application of electric vehicles, portable electronics, and large-scale energy-storage grids. 5,6 Nevertheless, several formidable challenges, including uncontrollable Zn dendrite growth and water-induced side reaction, leading to the low Coulombic efficiency and unsatisfactory working life, retard the commercialization of AZIBs. 7,8 The continuous growth of Zn dendrites on the Zn anode during cyclical Zn deposition/desolution can impale the separator and thus result in the short-circuit and failure of batteries.…”

“…The explosive growth of rechargeable aqueous zinc-ion batteries (AZIBs) in scientific research is ascribed to the advantages of low-cost, high safety, environmental friendliness, rich inventories of Zn metal, and high theoretical capacity (820 mA h·g –1 and 5855 mA h·cm –3 ). − Thus, AZIBs have been considered as one of the most promising candidates for high-density energy-storage systems in the application of electric vehicles, portable electronics, and large-scale energy-storage grids. , Nevertheless, several formidable challenges, including uncontrollable Zn dendrite growth and water-induced side reaction, leading to the low Coulombic efficiency and unsatisfactory working life, retard the commercialization of AZIBs. , The continuous growth of Zn dendrites on the Zn anode during cyclical Zn deposition/desolution can impale the separator and thus result in the short-circuit and failure of batteries. Besides, owing to the high reduction activity, the Zn metal anode can easily react with the water molecules in aqueous electrolyte, leading to the hydrogen evolution reaction (HER) and surface microcorrosion.…”
