BattAllox aims at targeting multiple electron transfer and tuneable redox properties for enhanced energy storage systems. Using bioinspired design principles and molecular engineering, this project focuses on interfacing redox-active isoalloxazine and alloxazine units with coordination chemistry to deliver highly tuneable and versatile redox systems. Redox behaviour at the molecular and higher levels will be studied on small-molecule organic units, organometallic complexes and Coordination Polymers. These redox species will be the basis of a new class of robust multi-electron transfer materials, for electrode materials, for example, and will be incorporated in redox-flow batteries. This multi-scale and multidisciplinary approach bring together molecular design, electrochemical studies, coordination networks and redox-flow batteries.
