Research progress on electrode structure design of vanadium redox flow battery
摘要
Abstract
The vanadium redox flow battery(VRFB)holds significant promise for large-scale energy storage applications.A key strategy for reducing the overall cost of these liquid flow batteries lies in enhancing their power density and operational efficiency.The electrode serves as the core site for the mutual conversion of electrical and chemical energy,with its structural characteristics and surface properties directly impacting electrochemical reaction rates,internal battery resistance,and electrolyte transport processes,thereby influencing overall battery performance.The synergistic enhancement of electrode transport and electrochemical performances can be achieved by developing macroscopic and microscopic ordered electrode structures.In this study,the structural design of electrodes from macro to micro scales and the research progress in VRFB.At the macro scale,we summarize and analyze how structural parameters such as electrode compression ratio,electrode flow field structure,and electrode geometric shape influence battery performance was analyzed.At the micro scale,single-layer electrodes with multilevel porous distributions as well as multilayered electrodes with gradient distributions using physical and chemical methods was constructed.These approaches can increase the specific surface area of the electrode,promote the electrochemical reaction,and improve the diffusion of electrolytes on the electrode surface.Finally,this study discusses the existing problems and propose future research directions for structured electrode design.关键词
