Composite electrodes embed the carbon felt electrode into conductive plastic bipolar plate by special process, can greatly improve electrical conductivity and battery efficiency.
Carbon plastic electrode for Vanadium redox flow battery is a kind of conductive composite material which uses polyethylene as adhesive, the active coating material is added on a side. The service life of VRB is mainly influenced by deterioration of Carbon-plastic composite electrodes. Therefore, technical indexes are critical to ensure optimum performance of batteries.
The bipolar plate for Zn-Br flow battery is a kind of carbon plastic electrode, it’s a carbon-based electrically conductive composite material that uses polyethylene as adhesive. The service life of Zinc Bromine batteries mainly influenced by deterioration of Carbon-plastic composite electrodes. Therefore, technical indexes are critical to ensure optimum performance of batteries.
Membrane separator is a porous membrane which provide a barrier between the the cathode (positive) and anode (negative), and prevent short circuit of the opposite electrodes. As one of the key materials for Zn-Br flow batteries, microporous membrane is monopolized by very few companies and the price is very high.
Proton-exchange membrane is also known as Ion-exchange membrane, is one of the key components in vanadium redox flow battery(VRFB) system. Poly(vinylidene fluoride) is used as the based material for proton conducting membrane, which offers stable chemical properties including good acid resistance and oxidation resistance.
The bipolar membrane is a kind of ion exchange membrane composed of positive and negative membranes. Both anions and cations cannot penetrate the membrane, and dissociate water into H+ and OH− ions, which migrate from the cation exchange layer and anion exchange layer respectively under the action of a positive DC electric field.
Graphite electrode has many advantages including high electrical conductivity and deal mechanical strength. Due to impregnated resin, graphite material can achieve gas impermeability and high strength, however, the material retains the favorable properties of graphite such as high thermal conductivity and high electrical conductivity.
Graphite soft felt for flow battery is a type of PAN-based battery felt with specialized fibers and weave which are suitable for liquid wetting and absorption. Carbon felt has properties of less chemically reactive and high conductivity.
Vanadium battery stack is the core part of vanadium redox flow battery which is manufactured by advanced processing technology and assembly process, assembled from independently-developed high-performance material components.
