Publication: Membrane-free redox flow battery: From the idea to the market

Due to their efficiency and ability to decouple energy and power density, redox flow batteries (RFBs) are particularly suited to address the rising energy demand and the need for effective energy storage systems. Still, the costs for ion-selective membranes and vanadium-based electrolytes used for those batteries are high. This publication considers and alternative membrane-free flow battery technology that relies on immiscible electrolytes which separate into two distinct liquid phases without the use of a membrane or other kind of separator. With this approach, current obstacles in RFB technology can be addressed which includes reducing the costs and increasing sustainability and overall performance. The publication likewise addresses the basics and next steps towards market implementation.
