The development of various redox-flow batteries for the storage of fluctuating renewable energy has intensified in recent years because of their peculiar ability to be scaled separately in terms of energy and power, and therefore potentially to reduce the costs of energy storage. This has resulted in a considerable increase in the number of publications on redox-flow batteries. This was a motivation to present a comprehensive and critical overview of the features of this type of batteries, focusing mainly on the chemistry of electrolytes and introducing a thorough systematic classification to reveal their potential for future development.

“…At the charge and discharge rate of 1 and 0.5 mA, respectively, the first cycle gave an energy efficiency of 74 % and the second cycle gave an energy efficiency of 57 %. Based on this work, a redox flow cell using Ru (acac) 3 as the active materials with two 2.5-L storage tanks and 5 cm × 5 cm active area was demonstrated [72]. For 0.02 M Ru(acac) 3 , the optimum power output was 3 ] 0 (negative electrolyte) was examined [75].…”

The paper first reports the use of a kind of positive electrode material (graphite/graphene-oxide composite) in zinc-cerium redox flow battery (RFB). It exhibits excellent electrochemical performance toward Ce 3+ /Ce 4+ redox couple in zinc-cerium RFB. The material was characterized with Xray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). The electrochemical activity of this kind of material to Ce 3+ /Ce 4+ redox reaction was studied with cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The results showed that the electrochemical performance of the electrode was improved significantly when 2.5 wt% graphene oxide (GO) was added into graphite electrode. The redox peak current of Ce 3+ /Ce 4+ couple on the composite electrode was significantly larger than that on the graphite electrode, and the charge transfer resistance on the composite electrode is also obviously reduced. The enhanced electrochemical activity could be attributed to the presence of plentiful oxygen-containing functional groups on the basal planes and sheet edges of the GO and large specific areas introduced by the GO. The energy efficiency of zinc-cerium RFB using graphite/GO composite as positive electrode is around 76.3 %, which is larger than that using graphite (65.9 %). The excellent results demonstrate that the graphite/GO composite holds great promise in the application of zinc-cerium RFB.
