摘要

We reported a novel cerium-copper redox flow battery and , the cyclic voltammetry characteristics of the Ce3+/Ce4+, Cu2+/Cu0 redox couples were studied .Moreover, a laboratory level redox flow battery was assembled to study the charge-discharge performance of this battery .The test result suggests that the battery delivers a desirable discharge voltage of approximately 1.0 V, with a high average coulombic efficiency(CE) of 100% and energy efficiency(EE) of over 75%during 100 cycles at 45 mA charge-discharge current.%设计了一种新型Ce-Cu氧化-还原液流电池，研究了Ce3＋／Ce4＋和Cu0／Cu2＋氧化还原电对的循环伏安特性，优化了电解液及电极材料，进而组装出液流电池，测试了电池的充放电性能。结果表明，在45 mA恒电流充／放电条件下，电池放电平台电压约为1.0 V，库伦效率约100％，能量效率为75％以上，电池可稳定循环100次。
