Abstract:Aqueous manganese redox flow batteries (AMRFBs) that
rely on the
two-electron transfer reaction of Mn2+/MnO2 have
garnered significant interest because of their affordability, high
voltage, and excellent safety features. Nevertheless, the deposited
MnO2 tends to partially dissolve during discharge, impeding
the sustained operation of AMRFBs, particularly at high areal capacities
(>5 mA h cm–2). Herein, VO2+/VO2
+ was introduced into the catholyte as a redox
mediator
(RM) to facilitate the efficient dissolution… Show more
