Abstract Aqueous zinc‐ion batteries (ZIBs) have generated extensive research attention for stationary energy storage, due to their advantaged superiority in terms of inherent safety, low cost, and eco‐friendliness. However, uncontrollable dendrite growth side reactions the Zn anode affect cycle life ZIBs. Conventional separators are almost ineffective inhibiting these issues. Herein, a chitin nanofiber membrane separator is developed tackle issues via simple, low‐cost, scalable strategy. The obtained exhibits abundant zincophilic functional groups, homogeneous nanopores, excellent mechanical properties, which facilitate desolvation hydrated 2+ ions, improve transference number, homogenize ion flux, simultaneously. Moreover, can also reduce deposition barrier, accelerate kinetics. Therefore, dendrites harmful effectively synchronously suppressed, enabling assembled ZIBs with an ultralong good rate capability. Impressively, Zn‐MnO 2 pouch cell stability safety under various external damages. above highlights mark significant step toward practical application

Biomimetic Inorganic–Organic Protective Layer for Highly Stable and Reversible Zn Anodes

ACS Energy Letters, Год журнала: 2024, Номер unknown, С. 337 - 344

Опубликована: Дек. 20, 2024

Uncontrollable dendrite growth and severe parasitic side reactions on Zn electrodes pose formidable challenges for the application of aqueous Zn-ion batteries. Herein, we engineered a biomimetic inorganic–organic protective layer composed alginic acid lithium magnesium silicate to enhance stability reversibility electrode. This not only diminishes free water concentration near surface but also creates negatively charged ion microchannels transport ions modulate solvation structure. Moreover, robust Mg-SiO2 interphase with high Young's modulus strong zincophilicity can be formed between electrode layer, facilitating uniform deposition along Zn(002) planes. Consequently, this allows achieve impressive cycling lifespan 5500 h at 1 mA cm–2/1 mAh cm–2 Coulombic efficiency 99.5% delivers remarkable cyclability up 8000 cycles in Zn||V2O5 full cells.

A Water‐Insoluble Yttrium‐Based Complex as Dual‐Ionic Electrolyte Additive for Stable Aqueous Zinc Metal Batteries

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Abstract Aqueous batteries employing Zinc metal anodes (ZMAs) are considered to be promising next‐generation energy storage systems. However, the severe interfacial side reactions and dendrite growth restrict practical application of ZMAs in aqueous electrolytes. Herein, a water‐insoluble dual‐ionic electrolyte additive yttrium 2,4,5‐trifluorophenylacetate (YTFPAA) is developed stabilize ZMAs. Notably, ethanol‐solvated TFPAA − can capture H + thus buffer decreased pH caused by hydrolysis Y 3+ . Furthermore, dynamically adsorb onto surface through reversible oxidation‐reduction reaction, effectively suppressing forming water‐poor interface, enhancing reversibility Zn 2+ deposition/stripping redistributing flux. These favorable effects combined with dynamic electrostatic shielding effect ultimately enable uniform dense deposition. As result, Zn/Zn cells assembled 0.25YTFPAA exhibit an impressive cycle life 2100 h at 0.5 mA cm −2 –0.25 mAh More importantly, V 2 O 5 /Zn full cell shows ultra‐long up 18000 cycles 5.0 A g −1 This work highlights rational design multifunctional ionic additives for stabilizing
