摘　　要：设计了平直并联和蛇形流道以及平整式和开孔式电极结构,比较了它们对全钒液流电池(VRB)性能的影响。在单体电池的充电电压为1.6 V,放电电阻为1Ω的情况下,蛇形流道和开孔式电极能够有效提升VRB的性能,能量效率分别比平直并联流道和平整式电极提高11.0%和8.7%。The straight parallel and snakelike channels, plane and hole-open electrode structures were designed, their effects on the performance of all vanadium redox flow battery （VRB） were compared. Under the condition of a charge voltage of 1.6 V and discharge resistance of 1 Ω with the single cell, the snakelike flow oriented structure and the hole-open electrode could obviously increase the efficiency of VRB. The energy efficiency was increased by 11.0% and 8.7% compared with straight parallel channel and plane electrode structure, respectively.
