| Abstract: | 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. |
