Abstract:

With the rapid development of renewable energy, redox flow battery, as a renewable energy storage system with high capacity, good flexibility, strong scalability and long cycle life, has attracted much attention in the industry. The bipolar plate, as an important part of redox flow battery stack, plays the role of supporting electrode, conducting current, connecting battery, supporting stack and separating positive and negative electrolyte. Due to the harsh working environment, the bipolar plate should have the characteristics of high electrical conductivity, good mechanical properties, good corrosion resistance, low permeability and chemical stability. Therefore, the current development of low-cost high-performance bipolar plates has become one of the key elements of the development of flow batteries. This paper focuses on the recent development status of carbon composite bipolar plates in redox flow batteries since 2010, including the influence of different flow field designs, different carbon-based materials and polymer materials on the conductivity, mechanical properties, permeability resistance, corrosion resistance and single battery performance. Finally, based on the current development requirements and key technical bottlenecks of carbon based composite bipolar plates, a brief analysis and outlook are made.
