摘要 :

As one of the most promising electrochemical energy storage systems, the vanadium redox flow battery (VRFB) has received increasing attention owing to its attractive features for large-scale storage applications. However, high production cost and relatively low energy efficiency still limit their feasibility. One of the critical components of VRFB that can significantly influence the effectiveness and final cost is the electrode. Therefore, the development of an ideal electrocatalyst with low cost, high electrical conductivity, large active surface area, good chemical stability, and excellent electrochemical reaction activity toward the VO2+/VO2+ and V2+/V3+ redox reactions are crucial for the design of VRFB. Extensive researches performed on the electrode modification routes for VRFB to improve the energy density and overall performance for large-scale applications. The seminar focuses on the state-of-the-art of numerous modification methods of the VRFB electrode, including the carbon materials, metal and metal oxide-based materials, and metal oxide/carbon composite materials.
