A team of Chinese and Finnish researchers has identified composite membranes as the best membrane for non-aqueous redox flow batteries (RFB) used in energy storage systems, PV Magazine writes in a recently published article.
Because the membranes of redox flow batteries account for a large portion of the final cost, researchers from Aalto University in Finland and Tianjin University in China conducted a review of the different kinds of membranes that could be used in non-aqueous redox flow batteries (NARFBs).
According to the team of researchers, NARFB is a second-generation technology with a much higher energy density and temperature window, compared to aqueous devices. Identifying which membrane technology that could simultaneously ensure high performance and low-cost production it could help bring redox flow storage closer to wider adoption in commercial projects.
The Chinese-Finnish research team’s review of all membrane technologies, “Membranes in non-aqueous redox flow battery: A review,” was recently published in the Journal of Power Sources.
