What is AOFB aqueous organic flow battery?
AOFB, aqueous organic flow battery. Most traditional flow batteries are based on ions of transition metals, represented by the vanadium flow battery (VFB) [,,, ]. VFBs employ vanadium ions with different valence states as electrolytes, i.e. V2+ /V 3+ as the negative electrolyte and VO 2+ /VO 2+ as the positive electrolyte.
