Abstract
The need for the development of effective storage methods for renewably generated electricity has become increasingly evident in the past few decades. With a growing need for the development of large-scale energy storage technologies, the redox flow batteries known for their high capacity, energy efficiency and low cost have attracted huge attention. Among all kinds of different flow batteries, Zinc-based flow batteries (ZBFB) and Vanadium flow batteries (VFB) are two of the most promising system. However, both systems suffer from low reaction rate and high overpotential caused by the low kinetics of 3D current collector as well as the membrane crossover issue. In this thesis, methods of improving electrode interfacial properties and the separator properties were introduced and were applied to both ZBFB and VFB system. Single cell testing, electrochemical measurements and SEM were done to analyze the mechanism behind it.
