Characteristics of a new all-vanadium redox flow battery

Journal of Power Sources, 1988
Abstract The construction and performance of an all-vanadium redox flow system is described. The battery employs vanadyl sulphate in sulphuric acid solution as the electrolyte, carbon felt as the electrode material, and an ion-selective membrane as the separator.

Determination of Overpotentials in All Vanadium Redox Flow Batteries

ECS Transactions, 2014
In this work we present a redox-flow battery set-up, into which two reference electrodes were inserted. This system allows for the investigation of individual overpotentials in each half-cell. Further, polarization (E/i) curves were recorded for different states of charge (SOC) of the battery.

Systematic Lumped Modeling of all-Vanadium Redox Flow Batteries

Journal of The Electrochemical Society, 2022
Recently, the lumped models for all-vanadium redox flow batteries (VRFBs) have gained a lot of interest among battery designers for system-level studies because of their simplified mathematical approach with the minimum computational procedure. In this paper, we, therefore, aim to systematically derive a reduced lumped mathematical model for VRFB.

Novel catalytic effects of Mn3O4 for all vanadium redox flow batteries

Chemical Communications, 2012
A new approach for enhancing the electrochemical performance of carbon felt electrodes by employing non-precious metal oxides is designed. The outstanding electro-catalytic activity and mechanical stability of Mn(3)O(4) are advantageous in facilitating the redox reaction of vanadium ions, leading to efficient operation of a vanadium redox flow battery.
