Multivalent organic batteries (Conference Presentation)

Multivalent organic batteries can be considered as sustainable, cheap and environmental friendly batteries with high energy density due to use of metal negative electrodes. Magnesium, calcium, aluminum metals can be successfully combined with redox active polymers after proper selection of electrolytes. Several challenges are facing multivalent batteries and further development is required. Redox mechanism in multivalent organic batteries is based on charge transfer on quinone groups, however depends on the electrolyte, besides multivalent cations (Mg2+, Ca2+, Al3+) also cation complexes or even partially solvated cations can be involved into charge transfer reaction. In this presentation, overview of recent achievements in our group on the field of multivalent batteries will be discussed with a focus on reaction mechanism and how different battery components can influence charge transfer reaction.
