Inhibition of Vanadium Cathode Dissolution in Zinc‐Ion Batteries on Thermodynamics and Kinetics by Guest Pre‐Intercalation

Advanced Energy Materials, Год журнала: 2024, Номер 14(25)

Опубликована: Апрель 12, 2024

Abstract Aqueous zinc‐ion batteries (AZIBs), recognized for their safety and environmental friendliness, hold significant promise large‐scale energy storage. However, the rapid capacity degradation resulting from dissolution of active cathode materials hampers advancement AZIBs. Here, Ru 0.2 V 2 O 5 ∙0.41H (RuVO) is synthesized with remarkable retention (98.2% over 5000 cycles at 10 A g −1 ). The pre‐intercalation 3+ enhances stability both intrinsic cycling structures, elevating Gibbs free suppressing V‐dissolution thermodynamically. Additionally, intercalation modulates potential surface Zn 2+ migration, leading to dominance in insertion/extraction mechanism, thereby kinetically impeding reaction. This study elucidates thermodynamics kinetics V‐based cathodes through a combination experiments, mechanism analyses, density functional theory (DFT) calculations.

ABSTRACT Given their high safety, environmental friendliness and low cost, aqueous zinc-ion batteries (AZIBs) have the potential for high-performance energy storage. However, issues with structural stability electrochemical kinetics during discharge/charge limit development of AZIBs. In this study, vanadium oxide electrodes organic molecular intercalation were designed based on intercalating 11 kinds charged carboxylic acid ligands between 2D layers to regulate interlayer spacing. The negatively group can neutralize Zn2+, reduce electrostatic repulsion enhance kinetics. intercalated molecules increased Among them, 0.028EDTA · 0.28NH4+ V2O5 0.069H2O was employed as cathode a specific capacity (464.6 mAh g−1 at 0.5 A g−1) excellent rate performance (324.4 10 g−1). Even current density 20 g−1, after 2000 charge/discharge cycles 215.2 (capacity retention 78%). results study demonstrate that modulation spacing through properties vanadium-based materials.
