With the wide deployment of renewable energy harvesting devices, such as solar cells and wind turbines, there is an urgency to develop high efficiency and economical energy storage systems to stabilize the intermittent and often unpredictable primary power sources before the power can be channelled to the grid safely or utilized for on-site loads. Redox flow batteries (RFBs) are regarded as promising electrochemical energy storage devices due to their special features of separable energy and power capacity. However, redox flow batteries tend to have lower energy densities than integrated cell architectures. Many approaches have been studied to improve the energy efficiency of RFBs. Among them, reducing shunt current loss and other parasitic loss is of great importance. This invention is capable of minimizing the shunt current in a redox flow battery through increasing the conductive path that exists between adjacent cells, without increasing maintenance cost or assembly complexity.
