锌溴液流电池电解液与隔膜技术研究进展
Advancements in electrolyte and membrane technologies for zinc-bromine flow batteries
摘要
Abstract
As the significance of clean energy grows,there is an increased and diverse demand for energy-storage technologies.Zinc-bromine flow batteries(ZBFBs)are efficient and sustainable medium and long-term energy storage technologies that have attracted attention owing to their high energy density,long life,and low cost.The system uses zinc and bromine as active materials to store and release energy in electrolyte solutions.In this study,we summarize the basic working principle and application background of ZBFBs,the optimization strategy,and the latest development potential of diaphragm and electrolyte.First,we introduce the charge-discharge mechanism and electrochemical behavior of zinc-bromine batteries.Subsequently,we analyze the key factors that affect the performance of the battery,including the composition and concentration of electrolytes,the type and structure of the diaphragm,and the development status of modification technology of the diaphragm.Specifically,we discuss how these modifications alleviate the zinc dendrite phenomenon,as well as improve bromine capture,mechanical properties,ion-exchange rates,and conductivity.We also discuss the optimization of electrolytes in alleviating zinc dendrite and improving conductivity and flow rate.Finally,we summarize the challenges in current ZBFB research and future development directions.We emphasize the importance of material innovation,system integration,and large-scale application in achieving high-performance and low-cost ZBFBs.This study aims to present researchers with the latest progress in ZBFB technology,thereby guiding future research directions and facilitating technological breakthroughs.关键词
