Li-ion battery technology is nowadays the selected technology for energy storage of electric vehicles and portable electronics. However, its sustainability and scalability are questionable due to the use of rare elements, such as Co, Ni and Li. Alternatives to the current Li-ion battery technology are under development, such as Li- S, Li-O2, beyond-Li technologies (like Na-ion, Mg and Al batteries) and various organic-based batteries.

Redox polymers that can be reversibly oxidized and reduced are gaining much attention as sustainable organic electrode materials to replace the aboved mentioned inorganic scarce materials. The main advantages are that redox polymers can be chemically tuned and biobased, thus enabling materials for new battery technologies such as paper batteries, organic redox flow batteries, polymer−air batteries, or flexible organic batteries. In this talk, we will present the synthesis and characterization of redox polymers having radical groups and a family of bio-based polyhydroxyanthraquinones. Their application as organic electrode materials in Li-Organic batteries will be also presented. [3,4]
