The rapid growth of the role of renewable energy sources dictates new requirements for the
electrochemical energy storage devices. Among them, redox flow batteries (RFBs) are regarded as a
promising technology, since their advantages of excellent scalability, low cost, easy fabrication and
operation, long lifetime, and safety. Today inorganic RFBs are penetrating the market, however, low
specific capacity in conjunction with with low electrochemical stability window of aqueous
electrolytes (≈1.5 V) and safety issues, hinders their wide-scale commercialization.
