全钒液流电池容量衰减与抑制技术研究进展
Research progress on capacity decay and inhibition technology of all-vanadium flow batteries
摘要
Abstract
The vanadium redox flow battery(VRFB)offers several advantages,including long service life,high safety,straightforward energy management,and the independent scalability of power and capacity.These characteristics make it well-suited for applications such as mitigating fluctuations in renewable energy generation,peak shaving and filling,and voltage and frequency regulation in modern power systems.In recent years,VRFBs have seen large-scale deployment.However,due to the intrinsic properties of core components—such as membranes,stack and pipeline configurations,and electrolyte composition—capacity decay remains a significant challenge during operation.To extend service life,improve energy efficiency,and reduce the frequency of maintenance tasks such as electrolyte rebalancing and ion concentration adjustment,extensive research has been conducted globally on mitigating capacity fade in VRFBs.This paper analyzes the causes of capacity decay from both mechanistic and technical perspectives,summarizing the state of research on the impacts of water and vanadium ion migration,self-discharge,side reactions,temperature,and concentration under various application conditions.It emphasizes the roles of membranes and electrolyte-related materials in influencing capacity retention,along with strategies that adjust flow rate,charge-discharge protocols,and active species concentrations to suppress capacity loss.Moreover,it reviews emerging technologies tailored to specific application scenarios that aim to inhibit capacity degradation.The insights presented herein provide guidance for maintaining electrolyte performance and overall battery capacity during long-term VRFB operation.关键词
