Bipolar plates are exposed to harsh conditions due to the acidic vanadium electrolyte and high potential differences which occur in vanadium redox flow batteries. Therefore, the material needs to fulfil good electrical conductivity, sufficient impermeability and mechanical stability as w
Bipolar plates are an important part of a vanadium redox flow battery, since they provide numerous purposes, while also adding to the cost. A flow field is, commonly, embossed on bipolar plates, which necessitates sophisticated machining [1, 2] and delivers electrolytes to the electrode .
In addition, the structures of the bipolar plates refer to the flow field designs on the surface. The advantages and disadvantages of these existing flow fields are described, and the tendencies for further optimization are also discussed.
A novel electrode-bipolar plate assembly has been developed and evaluated for application in the vanadium redox flow battery (VRB). It is composed of three parts: a graphite felt (electrode), an adhesive conducting layer (ACL) and a flexible graphite plate (bipolar plate). The ACL connects the electrode with the bipolar plate to an assembly.
