As the world leans more towards solar and wind power, the importance of efficient and reliable energy storage systems becomes paramount. This article delves into the intricate world of RFBs, particularly comparing […]
SCALE-UP OF THE kW SYSTEMS
Image source: pinflowes.com Online Meeting The UPJS and INO-HUB Energy held an online meeting with Pinflow Energy Storage. PFES is going to be the battery equipment provider, so a close relationship is expected to speed up the purchase process. During this meeting, the specifications for the kW test rig and the lab test rigs […]
BEST CANDIDATES FOR ORFB
Image source: http://www.ttk.mta.hu/ TTK, Budapest, Hungary After the first meeting, different synthetic routes were planned to afford new viologens and anthraquinones derivatives. R&D team (Igor Derr and Juan Asenjo) visit TTK to check the new results. Promising results in the synthesis of various electrolytes were accomplished and now these materials must be tested in single-cell […]
CARBON FELTS MODIFICATION
Among the different articles the importance of different components such as the bipolar plates, membranes, electrolytes on the battery performance has been depicted. But nothing has been reported about the place where the redox reactions take place, the electrodes. Commonly, carbonaceous electrodes are widely used in Redox Flow Batteries existing different alternatives such as carbon […]
DIFFERENT TYPES OF RFB BATTERIES
Currently, vanadium redox flow batteries (RFBs) are the most recognized among flow batteries. However, other RFB technologies also deserve attention; for example, Zn-Br2, Fe-Cr, Fe-Cd, Zn-Fe, and Zn-Ni systems. Vanadium redox flow batteries Among all the RFBs technologies, vanadium systems are the most well-researched. The use of vanadium ions in different oxidation states as catholyte […]
ION EXCHANGE MEMBRANE (IEM) SELECTION AND MODIFICATION
In the core of Redox Flow Batteries, we find the electrochemical cell where the battery is charged/discharged. The Ion Exchange Membrane (IEM) electrically separates positive and negative side of the battery allowing the pass of ions through its structure closing the electrical circuit. This component plays a vital role on the battery performance affecting the […]
MEMBRANE SELECTION
The primary function of the membrane in a redox flow battery is to transport ions between the negative and positive battery sides and prevent the passage of redox-active materials (vanadium ions in the case of vanadium redox flow batteries). Furthermore, it must prevent the excessive transfer of solvent (water). Many commercially available membranes and separators […]
FIRST APPROACH TO ORGANIC ELECTROLYTES
After three months collaborating with TTK (Budapest) and more in concrete Denes Konya research group, some new and reported organic electrolytes have been synthetized. The reported electrolytes serve as a first step being able to compare our Lab-cell design and set up with the reported data in the literature. In this way, InoHub R&D team […]
DEFINITION OF KPI FOR RFB MEMBRANES
Image source: https://www.cellfion.se/ Trying to study different alternatives regarding one of the most important but conflictive components of RFB, the Ion Exchange Membrane, INO-HUB Energy team contacted Swedish Cellfion company. Cellfion develops nanocellulose derived ion exchange membranes. These membranes could represent a green candidate that could significantly decrease the cost of the whole stack. During […]
