High-performance redox flow batteries for large-scale energy storage


Driven by grave concerns over the energy shortage and environmental pollution, the world is moving towards renewable energy sources at full speed. However, because of their intermittent availability and fluctuating intensity, the unregulated and direct use of renewables would destabilize the power grid, which presents an imperative need to develop efficient, stable and cost-effective large-scale energy storage systems. Among various technologies, redox flow batteries (RFBs) are attracting increasing attention from both academic and industrial fields due to their decoupled energy and power, excellent scalability, high safety and fast response. However, the critical issues, including low power density, low electrolyte utilization, poor cycling stability and high capital cost, have hindered the widespread commercialization of RFBs. In this talk, I will firstly focus on the key factors limiting the development of RFBs by analyzing the coupled transport and electrochemical characteristics. I will then present our recent progress in addressing these issues and developing high-performance RFBs.
