Abstract: As global demand for clean energy grows, energy storage technology becomes crucial for the widespread adoption of renewable energy sources. Organic redox flow batteries (ORFBs) have emerged as a promising solution due to their unique safety and environmental benefits. In contrast to conventional lithium-ion batteries, ORFBs utilize aqueous electrolytes, eliminating the production of harmful substances and significantly reducing risks to human health. A comprehensive overview of the fundamental principles, key components, current research advancements, and potential applications of ORFB technology is provided. Through an in-depth analysis, the critical role of ORFBs in facilitating energy transition and promoting sustainable development is demonstrated. By reviewing the latest research trends,the future prospects and direction for the evolution of energy storage technologies are proposed.
