Although organic active materials (OAMs) are widely studied in organic and aqueous batteries, there are still some challenges to overcome before large-scale commercialization.
Besides technical requirements, such as redox activity and suitable electronic and ionic conductivity, and sustainability aspects (cost, toxicity, abundance, ...), there is a myriad of practical parameters related to the stringent operation requirements of batteries as chemical energy storage devices which need to be considered at an early stage.
Graphite and its derivatives are currently the predominant materials for the anode. The chemical compositions of these batteries rely heavily on key minerals such as lithium, cobalt, manganese, nickel, and aluminium for the positive electrode, and materials like carbon and silicon for the anode (Goldman et al., 2019, Zhang and Azimi, 2022).
