flow batteries (RFBs) are promising energy storage candidates
for grid deployment of intermittent renewable energy sources such
as wind power and solar energy. Various new redox-active materials
have been introduced to develop cost-effective and high-power-density
next-generation RFBs. Electrochemical kinetics play critical roles
in influencing RFB performance, notably the overpotential and cell
power density. Thus, determining the kinetic parameters for the employed
redox-active species is essential. In this Perspective, we provide
the background, guidelines, and limitations for a proposed electrochemical
protocol to define the kinetics of redox-active species in RFBs.
