“…However, this is shortened in both operation modes from cycle to cycle, as expected because of the accelerated ageing caused by the membrane selected. Previous works showed higher capacity losses when the RFB is supplied with green energies such as solar or wind power ,. The higher crossover that the Nafion 117 membrane presents leads to self‐discharge reactions in each electrolyte and subsequent capacity losses ,.…”

This work reports, for the first time, the behavior of a Redox Flow Battery using nanoparticles based on graphene in the vanadium based electrolytes to act as nanofluids and working under a solar profile radiation (realistic conditions) for renew-able energy storage. It has been demonstrated that the use of graphene based nanofluids improves the performance of this energy storage system and enhances the durability of the redox flow battery.[a] Prof.

Summary One‐step electrochemical preparation of chlorine doped graphene coated electrodes was succeed by cyclic voltammetric method for the first time in the literature in this work. Because hetero atom and oxygen functional groups doped graphene‐based electrodes can improve the electrochemical performance of the battery with formed defects sides on the main structure of the electrodes, the modification of graphene‐based electrodes by chlorine and oxygen including functional groups such as ―Cl, ―ClO4, ―ClO3, ―OH, and ―C═O have been done by arranging of scanned potential in cyclic voltammetric treatment. The structural features of chlorine doped graphene electrodes were analyzed by scanning electron microscopic analysis. Chemical structures of the surface of the electrodes were elucidated by X‐ray photoelectron spectroscopy. Raman analyses were carried out to determine the optical properties of the electrodes. Chlorine doped graphene‐based electrodes were also used as positive electrode component of a vanadium redox battery for the first time in the literature. The electrodes showed great electrochemical performance as positive electrode materials of the battery.

“…A comparative study of some redox electrolyte systems with respect to their suitability as test systems for the evaluation of cell designs has been reported [44]. The use of RFBs in a changing energy landscape including growing use of renewable energy sources from the grid level down to localized applications, including details like CO 2 -footprint has been highlighted [45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64]. Availability of raw materials for RFBs has been addressed [65].…”

Flow batteries (also: redox batteries or redox flow batteries RFB) are briefly introduced as systems for conversion and storage of electrical energy into chemical energy and back. Their place in the wide range of systems and processes for energy conversion and storage is outlined. Acceleration of electrochemical charge transfer for vanadium-based redox systems desired for improved performance efficiency of these systems is reviewed in detail; relevant data pertaining to other redox systems are added when possibly meriting attention. An attempt is made to separate effects simply caused by enlarged electrochemically active surface area and true (specific) electrocatalytic activity. Because this requires proper definition of the experimental setup and careful examination of experimental results, electrochemical methods employed in the reviewed studies are described first.
