全钒液流电池离子导电膜的选择性
Selectivity of ion conductive membranes in all-vanadium flow battery
摘要
Abstract
Vanadium flow batteries(VFB)has received widespread attentions in energy storage applications in recent years due to its characteristics of large power,large capacity,high efficiency and high safety performance.As a key component of VFB,ion conductive membrane has a serious problem of vanadium ion cross contamination,which is easy to cause the loss of battery capacity and reduce the battery service life.Therefore,it is of great significance to deeply understand the selectivity of VFB ion conductive membrane and proton conduction.This paper provides a comprehensive review of the research progress in VFB,encompassing cation-exchange membranes,anion-exchange membranes,zwitterion-exchange membranes,and porous membranes.Analysis of vanadium ion permeation and proton transport across ion-conductive membranes is made,with a primary focus on the impact of membrane modification,ultrathin composite membrane design,optimization of membrane microstructures,and functionalization of ion groups on the selectivity and conductivity.The paper also makes a comprehensive discussion on the current balance between selectivity and conductivity in VFB ion-conductive membranes,offering valuable insights for the development of high-performance,cost-effective,and long-lasting ion-conductive membranes,as well as their commercialization.It also discusses the researches of the hydrogen bond network structure based on the proton conduction mechanism,porous conductive membranes,low-cost ultrathin composite films,and molecular dynamics simulation of ion transmembrane to improve the selectivity of VFB ion-conductive films.关键词
