Here we report our materials developmental accomplishments in pursuing high-performance ASO flow batteries.3A variety of promising ASO candidates have been identified with desirable redox potentials and kinetics. Our strategies to improve the solubilities, chemical stabilities, and system performance of these ASO materials will be discussed. We also have gained fundamental understandings of the key performance-limiting factors in determining chemical stability of these redox species and capacity degradation of flow systems. These insights can effectively guide future ASO materials development and improvement.
