Description
Technical Field
The invention relates to the field of a bipolar plate material of a flow battery, in particular to a bipolar plate of an all-vanadium flow battery and a preparation method thereof.
Background

The bipolar plate is used as a key component of the flow battery, plays a role of connecting single batteries in series to form an electric stack, and needs to have good conductivity, liquid resistance, chemical stability and certain mechanical strength.
The bipolar plate material mainly used at present is a hard graphite plate or a carbon-plastic composite material. The hard graphite plate has the characteristics of high conductivity, good liquid resistance and good chemical stability, but the practical application of the hard graphite plate is limited due to high cost and poor mechanical property. The carbon-plastic composite material is a bipolar plate material which is widely concerned at present, and has the main advantages of simple processing, low cost and easy realization of large-scale production. However, such materials are less conductive and in order to increase the conductivity, the content of the conductive filler in the material needs to be increased. However, too high a content of conductive filler may embrittle the plate and make it unsuitable for stack assembly. Therefore, it is necessary to develop a carbon-plastic composite bipolar plate with high conductivity and high toughness.
In order to pursue high power density and low internal resistance of the all-vanadium redox flow battery, high conductivity of the bipolar plate is required, and the content of the conductive filler is increased when the conductivity is increased. In order to prepare the carbon-plastic composite bipolar plate material with the bulk conductivity higher than 10S/cm, the mass fraction of the conductive filler is usually over 60%, at the moment, the polymer matrix contains a large amount of conductive filler, so that the viscosity is increased, the fluidity is reduced, and the forming processing is difficult.
