Cell schematic. Discharge mode is shown; the arrows are reversed for electrolytic/charge mode. AQDSH 2 refers to the reduced form of AQDS. Huskinson et al. Click to enlarge. Researchers at Harvard have demonstrated a metal-free organic–inorganic aqueous flow battery—a quinone–bromide flow battery (QBFB)—as an example of a class of energy storage materials that exploits the favorable chemical and electrochemical properties of a family of molecules known as quinones.
