Now you see (through) me: A modular vanadium redox flow cell is used to examine electrolyte distributions in carbon electrodes by synchrotron X���ray imaging. The impact of three different flow geometries on the flow dynamics is studied, and el

Highly porous carbon–carbon composite electrodes for the implementation in redox flow battery systems have been synthesized by a novel soft-templating approach. A PAN-based carbon felt was embedded into a solution containing a phenolic resin, a nit

A porous carbon electrode fully saturated with electrolyte is one crucial aspect of vanadium redox flow battery efficiency. It determines the electrochemically active surface area, provides more active sites for the reaction during operation, and pre

Two major limitations of Vanadium Redox Flow Batteries (VRFBs) are (1) The transport losses of getting the electrolyte into the electrode and to the reaction sites with minimum resistance and (2) Lack of access to all reaction sites due to relatively
