  • 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.
  • Features
  • Single cell voltage range : 1.2V ~ 1.6V (depending on Vanadium electrolyte composition)
    Cell current density : 40 ~ 100 mA / cm2 ( 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 bottom left picture below for details)

    ○  7 x 7cm
    ○  5 x 5cm
    ○  3 x 3 cm

    Custom reactive area sizes up to 20cm x 30cm can be requested at extra cost.
  • 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 icluded for immediate use.
  • 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).

  • External Dimensions
  • H 67 x W 126 x D 126 mm

  • Procedure for Testing Flow Cell -- click picture to enlarge

    A jig or pressing machine is required to tightly press the unit cell together, which effectively suppress leakage of cathode & electrolyte solutions during live tests.    Please order a hydraulic jig separately by click pic below left, or use your own jig.
    Warning : Never exceed a max. pressure of 0.5MPa to avoid damage on the flow cell.
    A peristaltic pump and battery analyzer can be ordered for making a DIY Flow Battery test system at low cost (please choose from related products below).
