  • Vanadium Redox Flow Cell Vanadium Redox Flow Cell Single Split Unit for Battery Research

    Vanadium Redox Flow Cell Single Split Unit for Battery Research EQ-VRB-C is splitable single unit flow cell for Vanadium Redox Flow Battery research; a battery technology which takes advantage of eliminating the use of rare earth metals. Most importantly, this battery kind holds the potential to be vastly scaled up for industrial applications while incurring a lower cost increase -- the storage capacity is scaled up by implementing a larger electrolyte storage tank (compared to lithium-ion cells in which the amount of active materials on electrodes need to be increased and are more costly to produce). Moreover, this type of battery is capable of being charged and discharged for over 10 times the life cycle of lithium ion cells with no capacity loss.    This split test cell features easy and fast assembly with convenient part replacement to facilitate research for flow cell cathode and electrolyte solutions. Product parameters Features: · Single cell voltage range: 1.2V ~ 1.6V (depending on Vanadium electrolyte composition)  · Cell current density: 40 ~ 100 mA / cm^2 ( maximum 4.9A of possible current draw for a 7cm x 7cm reactive area)    · Manifold Blocks are made of anti-corrosive PTFE materials to withstand acids · Large reactive area provides uniform and reliable test data · Cathode materials are changable according to the test conditions · Easy assembly and disassembly Reactive Area - Multiple Configurations  · Standard cell comes with 3 interchangeable frames and gaskets for testing multiple parameters (please click the bottom left picture below for details):  o 7x7cm o 5x5cm o 3x3 cm · Custom reactive area sizes up to 20cm x 30cm can be requested at an extra cost Compression Pressure · 87 PSI (0.6Mpa), ~300KG Force is recommended · 116 PSI (0.8Mpa) Max. Unit Cell Internal Structure (all components are included) All components, Manifold Blocks, Current Plates, Bipolar Plates, Gaskets, Frames, Carbon Felts, Membranes, O-Rings, liquid inlet and outlet ports, are included for immediate use. Please click here to order extra Internal Components if it is needed.       Bipolar Plates · High electrical conductivity, chemical resistance, and high mechanical strength for toughness · These highly flexible plates offer performance comparable to conventional graphite plates BUT have excellent resistance to breakage and have less defects · Only ~0.7mm in thickness, this keeps cells thinner when stacked compared to graphite plates ( porous and brittle in nature; needs to be thick structurally) · Needs frequent replacement, please order from the "Related Products" category below External Dimensions   ·  126mm (L) x 126mm (W) x 67mm (H)  Application Notes Vanadium Redox Flow Cell Sketch Photo Credit: Rahman, F.; Skyllas-Kazacos, M.
