Abstract: Conductive plastic bipolar plate of vanadium battery was prepared with polyethylene as the matrix, and graphite, activated carbon and carbon fiber as conductive agent. The results show that carbon fiber has greatly improved the conductivity performance, mechanical properties and corrosion resistance of bipolar plate. The volume resistivity of bipolar plates is less than 0.1Ω.cm with carbon fiber content within 1%. The bipolar plate with carbon fiber has 30% increase in the maximum tensile strength comparing with the bipolar plate with no carbon fiber, and tensile stress increased by 51% with 0.2% strain. The bipolar plate can meet the applications of vanadium battery with energy efficiency of 82.2%.
