Redox flow batteries—Concepts and chemistries for cost-effective energy storage

Matthäa Verena HOLLAND-CUNZ, Faye CORDING, Jochen FRIEDL, Ulrich STIMMING

Frontiers in Energy 2018, Volume 12, Issue 2, Pages 198-224 doi: 10.1007/s11708-018-0552-4

Abstract: Electrochemical energy storage is one of the few options to store the energy from intermittent renewableenergy sources like wind and solar.Redox flow batteries (RFBs) are such an energy storage system, which has favorable features over othertechnologies, e.g. solid state batteries, due to their inherent safety and the independent scaling of energyHowever, because of their low energy-density, low power-density, and the cost of components such as redox
