Publication: Nanoelectrochemical Platform for Elucidating the Reaction between a Solid Active Material and a Dissolved Redox Species for Mediated Redox-Flow Batteries

Mediated processes using a solid material, often called “solid booster”, have been proposed to increase the energy density in redox flow batteries (RFB). The strategy alters the energy storage in the dissolved redox species to a solid active material placed in a compartment of the device. Understanding the reaction kinetics of the dissolved redox mediator and the solid booster is crucial for proposing feasible pairs of solid boosters and dissolved redox mediators. At Ruhr-University Bochum, they demonstrate a nanoelectrochemical methodology to monitor the reaction between the dissolved species in solution and the solid active material electrodeposited in recessed carbon nanoelectrodes.
