摘要/Abstract

摘要： 全钒液流电池(VFB)的电堆由若干单电池叠合在一起组成,通过公共流道和电解液分配管路连通多个单电池,电堆内部的电势差引起电解液中的离子定向迁移,形成旁路电流导致能量损耗.本文分析产生旁路电流和能量损耗的电堆结构机制,利用等效电路模型计算电堆内部旁路电流的分布,提出抑制和减小旁路电流的措施.通过设计合理的电解液流动管路,能够有效减缓旁路电流的影响,减小充电/放电循环过程的电荷损失,提高储能过程的能量效率.

Abstract: All-vanadium redox flow batteries (VFBs) are made of a series of single cells connected in parallel and packaged into a stack. A common channel connects single cells and distributes positive or negative electrolyte into each cell. Due to the electric potential in the stack, vanadium ions migrate along a specific direction in the positive or negative electrolyte that flows through the common channel, leading to the formation of shunt current and hence energy loss. This paper analyses the causes of shunt current formation, develops a mathematical model based on the analyses, and provides strategies to constrain the formation of shunt current. It is found that the formation of shunt current and hence the associated energy loss can be effectively reduced through a proper design of the flow channels.

Key words: all-vanadium redox flow battery, shunt current, cross-over reaction, modeling
