This presentation describes the recent progress of the advanced redox flow battery technologies including both aqueous and non-aqueous systems. On the component level, new developments on the high energy density electrolyte, high selective membrane, and catalytic electrode will be reported. Novel high energy density electrolyte combined with their NMR and Raman based solvation chemistry study will be discussed.  Development of high selective membranes (Figure 1) will be reported. Performance of the niobium oxide nanorod based catalytic electrode (Figure 2) will be presented. In addition, we will briefly discuss the research and development on the nonaqeuous redox flow battery system.
