Review—Bipolar Plates for the Vanadium Redox Flow Battery

Bipolar plates are one of the key components vanadium redox flow batteries. They electrically conduct and physically separate adjacent cells in series provide structural support to stack. exposed harsh conditions due acidic electrolyte high potential differences which occur Therefore, material needs fulfil good electrical conductivity, sufficient impermeability mechanical stability as well long-term chemical electrochemical resistivity. This review provides a comprehensive overview carbon-polymer based composites preferentially applied for bipolar battery. It addresses composite materials, their production, properties, degradation mechanisms, designs costs. In addition, it covers challenges potentials further development optimization.
