Enhancing the energy density and stability of vanadium-based redox flow batteries via a dual active species strategy

Abstract

Introducing cerium into the positive electrolyte of vanadium flow batteries, a novel V/V-Ce redox flow battery with high energy density and excellent stability is developed. During an extended cycling process at 200 mA cm-2, the V/V-Ce redox flow battery reaching an average energy efficiency values of 65.4%, surpassing that of conventional all-vanadium flow battery.
