Vanadium-based oxides have received great attention as promising next-generation electrode materials due to their diversity in chemical compositions, unique open structures for fast diffusion with outstanding electrochemical properties and various oxidation redox couples. A recent review has even debated whether they “will become the future choice for metal-ion batteries”.[1]

My talk aims to contribute to a deeper understanding of the potential of vanadium-based oxides as versatile electrode materials for energy storage beyond lithium. In the course of the lecture, structural peculiarities, redox activity, electrochemical performance, structure-property relationships and metal-ion storage mechanism of selected examples will be presented, from V₂O₅ to vanadium oxide bronzes and hydrated vanadium oxides.
