锌-碘电池的挑战与机遇:从电极材料设计到储能机理
Bridging Materials and Energy Storage Mechanisms in Zn-I2 Batteries
摘要
Abstract
Zinc-iodine(Zn-I2)batteries have emerged as a compelling candidate for large-scale energy storage,driven by the grow-ing demand for safe,cost-effective,and sustainable alternatives to conventional systems.Benefiting from the inherent advantages of aqueous electrolytes and zinc metal anodes,including high ionic conductivity,low flammability,natural abundance,and high volumetric capacity,Zn-I2 batteries offer significant potential for grid-level deployment.This review provides a comprehensive overview of recent progress in three critical domains:positive-electrode engineering,zinc anode stabilization,and in situ characterization methods.On the cathode side,anchoring iodine to conductive matrices effectively mitigates polyiodide shuttling and enhances the kinetics of I-/I2 conversion.Advanced in situ characterization has enabled real-time monitoring of polyiodide intermediates(I3-/I5-),offering new insights into electrolyte-electrode interactions and guiding the development of functional additives to suppress shuttle effects.For the zinc anode,innovations such as pro-tective interfacial layers,three-dimensional host frameworks,and targeted electrolyte additives have shown efficacy in suppressing dendrite growth and side reactions,thus improving cycling stability and coulombic efficiency.Despite these advances,challenges remain in achieving long-term reversibility and structural integrity under practical conditions.Future directions include the design of synergistic electrolyte systems,and integrated electrode architectures that simultaneously optimize chemical stability,ion transport and mechanical durability for next-generation Zn-I2 battery technologies.关键词
