Redox Flow Batteries: Materials, Design and Prospects

The implementation of renewable energy sources is rapidly growing in the electrical sector. This a major step for civilization since it will reduce carbon footprint and ensure sustainable future. Nevertheless, these are far from perfect require complementary technologies to dispatchable this requires storage. In last few decades, redox flow batteries (RFB) have been revealed be an interesting alternative application, mainly due their versatility scalability. technology has focus intense research great advances decade. review aims summarize most relevant achieved years, i.e., 2015 until middle 2021. A synopsis different types RFB conducted. Particular attention given vanadium (VRFB), mature technology, but also emerging promising chemistries. An in-depth performed regarding main innovations, materials, designs. drawbacks future perspectives addressed.
