Nanostructured Electrocatalysts for All‐Vanadium Redox Flow Batteries

Chemistry – An Asian Journal, 2015
AbstractVanadium redox reactions have been considered as a key factor affecting the energy efficiency of the all‐vanadium redox flow batteries (VRFBs). This redox reaction determines the reaction kinetics of whole cells. However, poor kinetic reversibility and catalytic activity towards the V2+/V3+ and VO2+/VO2+ redox couples on the commonly used ...

Chloride supporting electrolytes for all-vanadium redox flow batteries

Physical Chemistry Chemical Physics, 2011
This paper examines vanadium chloride solutions as electrolytes for an all-vanadium redox flow battery. The chloride solutions were capable of dissolving more than 2.3 M vanadium at varied valence states and remained stable at 0-50 °C. The improved stability appeared due to the formation of a vanadium dinuclear [V(2)O(3)·4H(2)O](4+) or a dinuclear ...
